Question

A. los
B. la
C. el
D. las

Answer 1

I believe the answer is B

Answer 2

Right answer: la

In Spanish grammar the article is a word that clearly indicates the gender and the number of the noun. Its function is to modify the noun it introduces.

The articles are as follows:

Variable Articles:

Defined Articles:

Singular Masculine: el

Singular Femenine: la

Plural Masculine: los

Plural Femenine: las

Indefinite Articles:

Singular Masculine: un/uno

Singular Femenine: una

Plural Masculine: unos

Plural Femenine: unas

Invariable Articles:

Neutral: Lo

Contractions: al (a+el) and del (de+el)

Now, in this sentence muchacha (girl) is a feminine singular noun.

We also have more information: she is not any girl, she is Juan's sister.

Therefore, we must use the defined article for singular femenine she (ella), which is la:

Esta muchacha es la hermana de Juan

This girl is Juan's sister
