The verb, ser, is in the singular el/ella/usted tense, meaning that the subject is only one person or thing. This eliminates the two middle choices, as they are multiple people.
Next, the adjective. Alto is in the masculine form, so Maria, as it is a girl name, is also able to be eliminated.
The correct answer would be Tomas.

Answer: I think that you were suppose to complete the sentence. So instead of saying "No hay muchos." You were suppose to say "No hay muchos estudiantes en la Nebrija." I hope this helps. :)
