The mood for the given sentence is imperative. The correct answer is C.
The sentence which has a misplaced adjective phrase is:
<span>A. We saw a bird sitting on a branch with a long, yellow beak.
</span>
The correct sentence should be: "We saw a bird with a long, yellow beak<span> sitting on a branch." The adjective phrase "with a long, yellow beak sitting on a branch" should be placed directly after the noun bird which it modifies.</span>
