B Correct answer
Explanation

Simple interest is calculated as (P * R * T) / 100. Here, P = 800, R = 5, T = 3.5. Interest = (800 * 5 * 3.5) / 100 = 8 * 5 * 3.5 = 40 * 3.5 = 140. Total amount = 800 + 140 = 940.

AI explanation

Using the simple amount formula, Amount equals Principal plus Principal multiplied by Rate multiplied by Time divided by 100. Substituting the values gives 800 plus (800 multiplied by 5 multiplied by 3.5 divided by 100), which simplifies to 800 plus 140. Adding the principal and the interest of 140 gives the final amount of 940.
