La niña tiene un oso de peluche en su recámara.
Substitute "un oso de peluche" with a direct object pronoun and explain why you used the pronoun you chose.

La niña lo tiene en su recámara.
I used the pronoun "lo" because "un oso de peluche" is a masculine singular object, so the pronoun that represents it in the sentence should also be masculine singular, which is "lo".
