Select the option that is related to the third term in the same way as the second term is related to the first term:
$$\text{ER : VI :: JQ : ?}$$

Let's examine the relationship between the letters in the first pair $\text{ER : VI}$:
* E and V are opposite pairs in the alphabet (the sum of their positions is $5+22=27$).
* R and I are opposite pairs in the alphabet (the sum of their positions is $18+9=27$).

Following the same logic for $\text{JQ}$:

* The opposite letter of J is Q ($10+17=27$).
* The opposite letter of Q is J ($17+10=27$).

Therefore, JQ is related to QJ.
