If the first $10$ elements of series $I$ are picked up and written in reverse order followed by last $10$ elements of series $II$ without changing the order, which of the following pairs of elements will indicate $16^{th}$ element from the left and the $8^{th}$ element to its left respectively?

New Series = First 10 elements of Series I in reverse + Last 10 elements of Series II without reverse.

= #  \$  Z  B  4  5  *  Q  P  N  6  2  ?  U  A  3  9  @  I  S

16th element from left = 3

8th element to the left of (16th element from left) = Q

Thus answer = (3,Q). Option B.
