Answer :
Answer:
A
Step-by-step explanation:
B, C, D have only one specific answer and only one variable
But A has two variables to be found out: name of friend and the number of pet he or she has
for each and every friend
this number varies from friend to friend
so it is categorised and has a range of values not one answer
therefore A is statistical
I think it might be A, thats my first guess. But it might also be D.
