B Correct answer
Explanation

Simple interest = (P * R * T) / 100. P = 400, R = 15%, T = 18 months = 1.5 years. SI = (400 * 15 * 1.5) / 100 = 4 * 15 * 1.5 = 90.

AI explanation

Using the simple interest formula, the interest is calculated as (400 * 15 * 1.5) / 100, where 18 months is 1.5 years. Multiplying these values gives 9000 / 100, so the simple interest is Rs. 90.
