Climb the room and place a Power Bomb near the top before exiting G-mode.

Entrance condition:

{
  "comeInWithGMode": {
    "mode": "any",
    "morphed": false
  }
}

Requires:

"h_heatedGMode"
"h_usePowerBomb"
{
  "heatFrames": 0
}

Clears obstacles: A, B

Dev note: It is possible to do this with artificial morph, but progressing anywhere else in the room requires Morph. FIXME: It looks like the heat frames going up from 5 don't take into account that the Power Bomb blocks could already be broken.
