A ti (Tú) ____ gusta escribir correos electrónicos.

A ti te gusta escribir correos electrónicos.

A ti (Tú) te gusta escribir correos electrónicos.

To answer this question, you need to know the subject pronoun "tú" and the verb "gustar" in Spanish.

First, identify the subject pronoun "tú," which means "you" (informal/singular) in English.

Next, determine the correct form of the verb "gustar." The verb "gustar" is different from regular verbs because it expresses liking or preferences, and it is used in a different structure.

In this case, since the subject is "tú," you need to use the form of "gustar" that agrees with it. The correct form is "gusta" because "gustar" agrees with the third-person singular subject, which is "tú."

Putting it all together, the correct sentence is:

A ti (Tú) te gusta escribir correos electrónicos.

-The subject pronoun "tú" is usually optional and is included here for clarification.

- The word "te" is a reflexive pronoun that corresponds to "tú" and is necessary in this sentence structure.

The answer to the question is, "A ti (Tú) te gusta escribir correos electrónicos."
