B) se nos dan. you use Nosotros for plural form
It depends, what is on the list? If "playing, dancing, or singing " is on there than here you go:
-Angel and Lupita are playing.
-Angel and Lupita are dancing.
-Angel and Lupita are singing.
C. estaremos llegando
Why? Because it’s talks about us so you need to use the proper term. Estaremos refers to us. It translates to “Next next day at this same hour we will be arriving at the house.”
