Kill the Metroids while artificially morphed with just Spring Ball to avoid them. A Metroid (or a Rinka) must be completely on screen while a Power Bomb explodes in order for it to lure the other Metroids. Because of this, with extra ammo, it is possible to kill one or two of them before luring the rest. In general, this seems to be easiest by minimizing Samus's horizontal movement as much as possible and getting the Metroids in sync with each other while circling around her. While moving horizontally, their movement is less predictable and harder to sync. Note that it is necessary to exit G-Mode before exiting the room in order for the Metroids to remain killed.

Aim the leftmost Rinka to travel horizontally across the top of the room and use it to damage boost between the two floating platforms. Killing the Rinka will normalize it's respawn timer, which may help in setting up the correct angle. Let the Rinka stay far enough ahead of Samus that she can jump the full distance to the first platform without hitting it. And then once it has reached the right edge of the platform, use it to damage boost.

Aim the ceiling Rinka to travel horizontally across the top of the room and use it to damage boost between the two floating platforms. Killing the lower Rinka shortly before killing the higher Rinka will synchronize their respawn timers so that Samus can jump when the lower Rinka reappears in order to get a good angle on the higher Rinka. Jump to the floating platform ahead of the high Rinka, jumping extra high to lead the Metroid out of the way if it is alive. Jump into the Rinka once it reaches the left edge of the platform to reach the next platform. Then use I-frames to pass through the Metroid if it is still alive.

While on the first platform, perform a long jump to the left then diagonally spark low into the side of the next platform. This will put Samus into a position where the Metroid will swoop underneath her.

This is easiest by staying on the top floating platform with the two Metroids stuck below it. Note that it is necessary to exit G-Mode before exiting the room in order for the Metroids to remain killed.

Kill the Metroids while artificially morphed with just Spring Ball to avoid them. A Metroid (or a Rinka) must be completely on screen while a Power Bomb explodes in order for it to lure the other Metroids. One strategy for this location is to wait for the Rinkas to fire twice, then place a Power Bomb in the hallway to the right and return to lure one. Jump over it twice and at the top of the second jump place a second Power Bomb; this one will explode when the other two Metroids arrive. Jumping high to the right can also help get them stuck in the top right corner while placing a Power Bomb. Note that it is necessary to exit G-Mode before exiting the room in order for the Metroids to remain killed.

Kill the Metroids while artificially morphed with just Spring Ball to avoid them. A Metroid (or a Rinka) must be completely on screen while a Power Bomb explodes in order for it to lure the other Metroids. Start the room with a bomb boost spring ball jump or a precise horizontal bomb boost. In general, this seems to be easiest by minimizing Samus's horizontal movement as much as possible and getting the Metroids in sync with each other while circling around her. While moving horizontally, their movement is less predictable and harder to sync. Note that it is necessary to exit G-Mode before exiting the room in order for the Metroids to remain killed.
