B Correct answer
Explanation

Simple Interest = Amount - Principal = 195 - 160 = 35. Formula: SI = (P * R * T) / 100. 35 = (160 * 7 * T) / 100. 35 = 11.2 * T. T = 35 / 11.2 = 3.125 years.

AI explanation

Using the simple interest formula, the interest earned is 195 - 160 = 35. Plugging in the known values gives 35 = (160 * 7 * T) / 100. Solving for T gives T = (35 * 100) / (160 * 7) = 3500 / 1120 = 3.125 years.
