Correct answer: A

The question asks for the time in years, but the options provided are labeled in "months." Based on the mathematical calculation, the correct answer is 3 years (which is 36 months).

Step-by-Step Solution

  1. Formula: The formula for Simple Interest is: Simple Interest = (Principal * Rate * Time) / 100

  2. Plug in the given values:

    • Simple Interest = 1800

    • Principal = 6000

    • Rate = 10%

    • Time = T (in years)

  3. Solve the equation:

    • 1800 = (6000 * 10 * T) / 100

    • 1800 = 600 * T

    • T = 1800 / 600

    • T = 3 years.
