Answer 1

Estoy seguro de que mi hermana querrá ver esa película.

Answer 2

Querer is the infinitive form of the verb, querrán es the future third person plural, querrá is future third person singular, and querré is future first person singular. So in this case, "mi hermana" can be changed to "she" which is third person singular hence the correct answer is "querrá"
