Refer to the letter and symbol series, and answer the question that follows.
(Left) K B # A @ S * B Q @ R V N % & S (Right)
How many letters are there between the element that is third from the right end and the element that is sixth from the left end of the given series?

Given: ​(Left) K B # A @ S * B Q @ R V N % & S (Right)

Logic:  The number of letters between the element that is third from the right end and the element that is sixth from the left end.

The third element from the right end is %.

The sixth element from the left end is S.

The elements between % (third from the right) and S (sixth from the left) are: * B Q @ R V N

There are 5 letters between the element that is third from the right end (%) and the element that is sixth from the left end (S).

Thus, the correct option is (b) 5
