Suppose that $E_1$ and $E_2$ are two events of a random experiment such that $P(E_1) = \frac{1}{4}$, $P(E_2 / E_1) = \frac{1}{2}$ and $P(E_1 / E_2) = \frac{1}{4}$. Observe the lists given below. The correct matching of List-$I$ from List-$II$ is:

List-$I$	List-$II$
$(A)$ $P(E_2)$	$(i)$ $1/4$
$(B)$ $P(E_1 \cup E_2)$	$(ii)$ $5/8$
$(C)$ $P(\bar{E}_1 / \bar{E}_2)$	$(iii)$ $1/8$
$(D)$ $P(E_1 / \bar{E}_2)$	$(iv)$ $1/2$
	$(v)$ $3/8$
	$(vi)$ $3/4$

• A
  $(A)$-$iv$, $(B)$-$ii$, $(C)$-$vi$, $(D)$-$i$
• B
  $(A)$-$iv$, $(B)$-$v$, $(C)$-$vi$, $(D)$-$i$
• C
  $(A)$-$iv$, $(B)$-$ii$, $(C)$-$vi$, $(D)$-$i$
• D
  $(A)$-$i$, $(B)$-$ii$, $(C)$-$iii$, $(D)$-$iv$
