Question 4 of 10 chico es mi amigo. A. EI B. La C. Uno D. Los

A

The question provides a sentence fragment "chico es mi amigo" which translates to "boy is my friend" in English. The task is to find the appropriate article that fits before "chico". In Spanish, masculine singular nouns like "chico" take the masculine singular definite article "El". Among the given options, "EI" (which is likely a typo and should be "El") is the correct choice. "La" is a feminine singular definite article and would not match with the masculine noun "chico". "Uno" means "one" and "Los" is the masculine plural definite article. Hence, the correct answer is "El", option A.
