Carlos es un chico muy a. ordenada b. gusto c. estudiosos d. simpático

Carlos es un chico mu simpático.

Explanation: The sentence that we have is:

"Carlos es un chico muy "

Here the subject is Carlos, that is a name for a male and is a singular subject.

The options are:

A) Ordenada: (as most adjetives finished in -a, this is a feminine adjetive, so this is incorrect)

B) Gusto ( This is not an adjetive)

C) Estudiosos (this ends in -s, which means that this is a plural adjetive, so this is incorrect)

D) Simpático (This is singular and masculine, so this is the only option that makes sense)

Carlos es un chico mu simpático.
