Answer: The correct options are 1, 2 and 4
Explanation: Grammatically correct means that the complete sentence has coherence.
1) Andrea Capizzani Suárez tiene 18 años means (Andrea Capizzani Suárez is 18 years old)
This has coherence and is correctly grammatically.
2) Andrea Capizzani Suárez usa uniforme en la escuela (Usa uniforme en la escuela uses uniform in the school)
This is correctly written.
3) Andrea Capizzani Suárez su horario del colegio es de 8:00-4:00. (Andrea Capizzani Suárez her school schedule is from 8: 00-4: 00.)
