Prime factorization of Quantity A yields 2^4*3*5*7 and of quantity B yields 2^5*3*5*7. So, clearly, quantity B is greater.

Explanation
Compare the quantities, looking for ways that the numbers in one quantity can be rewritten using the numbers from the other quantity. In Quantity A, rewrite 420 as 4 × 105.
The 105 values cancel out, and the remaining multiples of 2 also cancel except for one 2 left in Quantity B. Choice (B) is correct.
