Wording seems ambiguous here.
Clearly A has more unique prime factors (2 versus 1), but the stem asks about PRIME factors and does not specify unique or distinct.
Quanity A- includes \(2^{2}\) and \(3^{1}\) so there are 3 instance of prime factors as the stem asks for
Quantity B- is\( 2^{6}\) and includes 6 instances of prime factors.64 has 6 prime factors (2*2*2*2*2*2) and 1 unique prime factor(2)
Would it not be reasonable to conclude B based on how this question is worded in not specifying unique prime factors?
