Me leer libros de poesía cuando tengo tiempo libre. a. encanto b. encanta c. encantan d. encantamos

The correct answer is option B. Encanta.

Explanation:

This sentence is written in the present simple tense.

This tense is used to describe actions that are usually routines, habits, or something that happens now, at this time.

In this case we have the phrase "Me encanta leer libros de poesía cuando tengo tiempo libre." Of all the options given, you have to see which one is best suited to the unstressed personal pronoun "me", and also be in the present simple, since it is indicating a habit, something that this person does in his spare time.

Next I will write each unstressed personal pronoun with the verb "Encantar" conjugated:

Yo ---Meencanta

Tú---        Te encanta

Él/Ella/Usted---  Le encanta

Nosotros/as--- Nos encanta

Vosotros/as--- Osencanta

Ellos/Ellas/Ustedes Les encanta
