Fill in the blanks to complete the sentence:

I want to run through the jungle, the wind ___ my hair and the sand ___ my feet.

The correct answer is option D, "in" and "at."

In the given sentence, the phrase "the wind in my hair" means that the speaker wants to feel the wind blowing through their hair. Similarly, the phrase "the sand at my feet" means that the speaker wants to feel the sand beneath their feet. Therefore, the correct prepositions to use in the sentence are "in" and "at," respectively.

The other options are not appropriate because they do not convey the intended meaning of the sentence. "With" and "under" do not fit the context of running through the jungle and do not make sense in this sentence. "On" and "over" could work in some contexts, but they do not accurately convey the desired meaning of feeling the wind in one's hair and the sand at one's feet.
