I saw him resting . . . . . . . the shade of a tree.

below
into
under
in

The correct answer is D. in.

The other options are not correct because:

  • A. below is not a preposition that can be used with the word “shade.”
  • B. into is not a preposition that can be used with the word “shade.”
  • C. under is a preposition that can be used with the word “shade,” but it does not make sense in the context of the sentence.

The sentence is about a person who is resting in the shade of a tree. The preposition “in” is used to indicate that the person is inside the shade of the tree. The other options do not make sense in the context of the sentence.
