Answer 1

I can’t see the picture, but you can answer this by thinking about sunlight. Photosynthetic plants need the photic zone (about the top ~200 m). So the spot farthest down—the deep ocean (abyssal plain or trench)—would be least likely to have plant life.

So pick the letter that labels the deepest part of the seafloor (the trench). If the deepest point in the diagram is X, choose X; if it’s Y, choose Y, etc. If you want, upload or describe the diagram and I’ll pick the exact letter.
