Question

Which phrase correctly completes this conversation?

Answer 1

The answer is D - La conozco

Answer 2

Answer:

la conozco

Explanation:

Ana, ¿conoces a la maestra de historia?

Sí, yo la conozco

Translation:

Ana, do you know the history teacher?

Yes, I know her

In the first place we discard the option "la se" since in Spanish the use of the verb "saber" with respect to this sentence would not make sense. Then the gender is determined, in this case we are talking about the history teacher, therefore it belongs to the third person of the singular "la".
