Answer:
D.) Gusta
Step-by-step explanation:
Yo gusto Nosotros/Nosotras(We, males/females) gustamos
Tu gustas Vosotros/Vosotras(You all, males/females) gustain
el/ella Usted (He/She/you Formal) Gusta ellos/ellas Ustedes (They(males/females/You all) Gustan
This The changing AR verb for present not past so your changing the last letter of GUSTAR taking away the AR and putting it differently starting with (You/I/He/She/We/You all/ They)
Hope this helps
