Question

Select the answer that best completes the sentence. __________ mochila es negra. La El Los Las

Answer 1

La :)

Answer 2

Just to further explain what @KendrickLamar2014 said:

La - singular feminine
El - singular masculine
Los - plural masculine
Las - plural feminine

"Mochila" is the subject that you need to find the gender and if it is plural or not. It is not plural, it is singular, and the "a" in the end tells us it is feminine, so it is "la".

Good job @KendrickLamar2014 . c;
