We have a range of 2...100.

Only some of the even integers will not be divisible by odd numbers in this range.

Let's try to list a few even numbers in the range: 2,4,6,8,10,12,14,16,18,20....

Out of these 2,4,8,16 are not divisible by odd factors - it can be deduced that the numbers we seek are multiples of 2: 2,4,8,16,32,64.

Therefore, the answer is B.
