$B = \{x : x$ is a divisor of $28\}$ in roster form is—

a $\{2, 4, 7, 14\}$
b $\{1, 2, 4, 7, 14, 28\}$
c $\{1, 2, 4, 28\}$
d $\{1, 28\}$

ব্যাখ্যা

The divisors of $28$ are all positive integers that divide it exactly: $1, 2, 4, 7, 14$ and $28$ itself. Listing every divisor gives the complete six-element set.
