Answer:
C
Explanation:
To make it easier to answer let's translate the sentence
It would say, " My cousin is the ___ of my grandmother."
The answer choices would be
A Grand daughter
B Aunt
C Grandson
D Uncle
Now let's find the answer.
So we know for a fact that their cousin is male because of the ending in primo
Ending o = masculine and ending in a = feminine
So we can immediately eliminate a and b
We also know that cousin = child of uncle and aunt. And we know that either your uncle or aunt is a sibling of your parents. Which leads to one of them having the same parents ( or your grandparents) . This means that your parents siblings child ( cousin ) has the same grandparents.
So we can conclude that your cousins (male) is a grandson of your grandma
