A is in the you (familiar) form, the verb 'sacas' gives a clue (ends in -s). So the answer is Tu.
B is in the they form because of the verb 'toman (ends in -n or -an)', so that is Paco y Pablo.
C is in the we form because of the verb 'escuchamos' (it ends in -amos), so it is Ella y yo (She and I, or Ella)
D is in the he/she/it form because of the verb estudia (ends in -a), so that is Ella (she or Ella)
E ends in -o, so it is in the I form (saco), the answer is Yo (I).
Merry Christmas!
