(B) The identity element $e$ in a group $(G, 	imes_{15})$ must satisfy $a 	imes_{15} e = a$ for all $a \in G$.From the composition table,we observe the row corresponding to $6$ reproduces the elements of $G$ in the same order.			$	imes_{15}$		$3$		$6$		$9$		$12$				$3$		$9$		$3$		$12$		$6$				$6$		$3$		$6$		$9$		$12$				$9$		$12$		$9$		$6$		$3$				$12$		$6$		$12$		$3$		$9$	Since $3 	imes_{15} 6 = 3$,$6 	imes_{15} 6 = 6$,$9 	imes_{15} 6 = 9$,and $12 	imes_{15} 6 = 12$,the identity element is $6$.

In the group $(G, \times_{15})$,where $G = \{3, 6, 9, 12\}$ and $\times_{15}$ is multiplication modulo $15$,the identity element is
