Clears obstacles: C

Dev note: FIXME: This could be possible without a hit, but requires precise timing and some luck, it helps to have a way to one hit kill one of the hoppers on the descent. Bomb spread can work, but also requires some patience and knowledge how to preserve the charge partway through the tunnel. A Power Bomb also works, but will clear B, Samus can just go 4->10->13.
