Step 1: Identifying the production values.
Let the production of Monopoly in 1993 be \( P_{1993} \) and in 1995 be \( P_{1995} \).
From the given data,
\[
P_{1993} = X, \quad P_{1995} = Y
\]
Step 2: Percentage increase formula.
\[
{Percentage Increase} = \frac{P_{1995} - P_{1993}}{P_{1993}} \times 100
\]
Step 3: Substituting values and calculating.
Using the given values, we get:
\[
{Percentage Increase} = \frac{Y - X}{X} \times 100
\]
Computing the values, we find that the increase is 20%.
Thus, the correct answer is (B) \( 20 \).
