$A = \{7, 14, 21, 28\}$ in set-builder form is—

a $\{x : x$ is a multiple of $7$ and $0 < x \le 28\}$
b $\{x : x$ is even and $x < 30\}$
c $\{x : x$ is prime and $x < 30\}$
d $\{x : x$ is odd $\}$

ব্যাখ্যা

Every listed element $7, 14, 21, 28$ is a positive multiple of $7$ that does not exceed $28$ . The condition " $x$ is a multiple of $7$ and $0 < x \le 28$ " generates exactly these four numbers.
