Los estudiantesla lección
A. comprenden
B. beben
C. leen
D. hacen

A. comprenden

Explanation:

Let's first translate this sentence:

"Los estudiantes" refers to "the students"

"la leccion" refers to "the lecture"

So, we want to find a relationship between the students and the lecture.

We need to see which answer choice will make the most sense here. Examine each one:

A) "Comprenden" comes from "comprender" which means "to comprehend/understand"; well, that makes sense here if the students understand the lecture, so keep this.

B) "Beben" comes from "beber" which means "to drink"; that doesn't make any sense here: students don't drink a lecture.

C) "Leen" comes from "leer" which means "to read"; while sometimes, it's true that you can read a lecture, usually lectures are in spoken form, so comprehending the lecture (choice A) makes more sense than C.

D) "Hacen" comes from "hacer" which means "to do"; that doesn't make sense here, either, because students don't "do" a lecture.

Thus, the answer is A.
