B is the right answer.

Well said @Ogundele D.

Multiplying constant (K) = 100.
Additive constant (C) = 0.
So, B is correct.

According to me, B is the right answer.

Nice, well said @Ogundele.

Actually, analytic lense only renders the additive constant to 0. It does not have any effect on multiplying constant.

Option A is the right answer.

The formula most widely used for finding the distances is:
d = k * s + c.

Here, s is the stadia interval (top intercept minus bottom intercept); k and c are additive and multiplicative constants. Generally, the instrument is made so that k = 100 and c = 0 exactly, to simplify calculations.
