Chico es mi amigo.
O A. Uno
O B. La
O C. Los
O D. EI

The answer should be D. El.

Explanation:

This problem was sort of hard to interpret at first, but it sounds as if you are identifying the Spanish pronoun associated with Chico. Therefore, since it is a singular person and not referring to a group, and amigo is used with a masculine ending, it can be inferred that the answer is D. El.

guatemala is the correct answer
