C Correct answer
Explanation

Difference between CI and SI for 2 years = P * (r/100)^2. 100 = P * (14/100)^2 = P * (0.14)^2 = P * 0.0196. P = 100 / 0.0196 = 5102.04.

AI explanation

Using the formula for the difference between compound interest and simple interest for two years, the difference equals Principal multiplied by (Rate divided by 100) squared. Substituting the given values, 100 equals Principal multiplied by (14 divided by 100) squared. Solving for the Principal gives 100 divided by 0.0196, which equals 5102.
