Choose the correct form of the verb in parentheses based on who or whom is in each sentence

¿Tù ___ (tocar) la guitarra?

O tocáis
O tocas
O tocan
O tocamos

¿Tú tocas la guitarra?

The correct answer is "O tocas" because "tú" is the subject, and "tocar" is conjugated in the second person singular form.

To determine the correct form of the verb, we need to identify the subject of the sentence. In this case, the subject is "tú" (you, singular informal). Since "tú" is the second person singular, the correct form of the verb "(tocar)" is "toca".

Therefore, the correct answer is: O tocas
