The quickest approach here is to simply calculate each value with your on-screen calculator.
Alternatively, we can rewrite each power with the same base. In this case, 64 and 16 can be expressed as powers of 4 and then simplified (using the Power of a Power rule) to get:
QUANTITY A: 643=(43)3=49
QUANTITY B: 165=(42)5=410
Answer: B
