Ana y Marta muy elegantes y para ir a la fiesta. A.
se despiertan, se duchan
B.
se visten, se maquillan
C.
se peinan, se cepillan
D.
se preparan, se duchan

I think it’s d because if you reread it and try it with them d sound good

It’s B
Explaining it is B because in English it would say “Ana and Marta dress very elegant and they do their makeup to go to the party.”

I’m a native Spanish speaker hope this helps!
