Explanation:

First Question

In Spanish, after "es importante que" (it's important that), we use the subjunctive mood. The verb "sentirse" (to feel) in the subjunctive for "él" (he) is "se sienta". "Se siente" is indicative, and "se sent..." is incomplete.

After "quieren que" (they want that), we use the subjunctive mood. The verb "hacer amigos" (make friends) in subjunctive for "Javier" (he) is "haga". "Hace" is indicative, and "haran" (spelling error, should be "harán") is future.

After "Es posible que" (It's possible that), we use the subjunctive mood. The verb "tener" (to have) in subjunctive for "Javier" (he) is "tenga". "Tiene" is indicative, "tendrá" is future.

Answer:

B. se sienta
