Answer:
b. estudiemos
Explanation:
In order to solve this, we have to remember reading the context, as you can see there are three options, and all are different conjugations of the verb Estudiar, since she talking of what she is doing with her familiy, the subject is "we" and we have to conjugate the verb estudiar for "we"in the subjunctive tense:
Yo estudie
Tu estudies
El estudie
nosotros Estudiemos
So the correct option to complete the phrase would be "B.Estudiemos"
