Hello!
To do these exercises, keep that in mind:
I/We/You/They → Normal verb form.
He/She/It → Verb + S/ES (like "drink", which becomes "drinks", or "go", which becomes "goes").
All these rules with Present Simple Tense.
Check out your answers bellow:
A) I work at the market.
B) That boy studies a lot for the exams.
C) We don't play basketball very well.
D) They play soccer very well.
