B Correct answer
Explanation

For 2 years, CI - SI = P * (r/100)^2. CI - SI = 6400 * (12.5/100)^2 = 6400 * (1/8)^2 = 6400 / 64 = 100.

AI explanation

For two years, the difference between simple interest and compound interest is calculated using the formula principal times the square of the rate divided by 10000. Substituting the values gives 6400 times 12.5 squared divided by 10000, which equals 6400 times 156.25 divided by 10000, resulting in Rs. 100.
