C Correct answer
Explanation

Simple interest formula is I = (P * R * T) / 100. Here, I = 256, P = 1200, and T = 1 year 4 months = 4/3 years. 256 = (1200 * R * 4/3) / 100 => 256 = 16 * R => R = 16%.

AI explanation

Using the simple interest formula, the time period is 1 year and 4 months, which equals 1 + 4/12 = 4/3 years. Plugging in the values gives 256 = (1200 * R * 4/3) / 100. Solving for R yields R = (256 * 100 * 3) / (1200 * 4) = 16%.
