<br>(B)<br>
All the elements of set (A) are even numbers between 1 and 21.
(C) is the empty set; it is a subset of every set.
(D) the integers between 3 and 23 that are divisible by 4 are all even numbers between 1 and 21.<br>
But (B) contains the element 0, which is NOT an even number between 1 and 21.
