The correct answer is D) Finding the baby bird on the ground, Maya returned it to its nest.
A modifier refers to a phrase or unit of a sentence that gives more information about, or describes something or someone. Options A, B, C do not use modifiers correctly, because the modifiers are misplaced. This means that it is difficult to tell what the modifier is referring to. For instance, in Option B: "Gazing up in wonder, the mountains looked enormous" it is unclear who is "gazing up in wonder". Option D is correct because it is clear that Maya is the one who found a baby bird on the ground.
