Answer:
The verb form that correctly completes the conversation is:
- C. <em><u>Compré</u></em><em>.</em>
<em>- Pedro: </em><em>¿Qué libro compraste en la librería? </em>
<em>- Luis:</em><em> Yo </em><em><u>compré</u></em><em> un libro de historias de ficción.</em>
Explanation:
The translation of the sentences in the conversation are:
- Pedro: What book did you buy in the bookstore?
- Luis: I bought a book of fiction stories.
The verb <em>"comprar"</em> <u>conjugated in </u><u>Simple Past</u><u> depends on the personal pronoun that modifies its conjugation</u>, to understand this, next I will show you the possible conjugations depending on the personal pronoun that is used:
- <em>Yo </em><u><em>compré</em></u><em>.
</em>
- <em>Tú </em><em>compraste</em><em>.
</em>
- <em>Él </em><em>compró</em><em>.
</em>
- <em>Ella </em><em>compró</em><em>.
</em>
- <em>Ello </em><em>compró</em><em>.
</em>
- <em>Nosotros </em><em>compramos</em><em>.
</em>
- <em>Ellos </em><em>compraron</em><em>.
</em>
As you can see, despite the multiple forms that the verb can have in the simple past, the conjugation that applies to the personal pronoun <em>"yo"</em> is <u><em>"compré"</em></u>.
