B Correct answer
Explanation

The profit percentage can be calculated if we know the discount (12.5%) and the relationship between CP and MP. Statement I gives the absolute value of the discount, Statement II relates SP to CP, and Statement III gives CP. Any one of these is sufficient to find the missing link to calculate the profit percentage.

AI explanation

Let the marked price be M, the selling price be S, and the cost price be C. The selling price is 0.875M, so the profit percentage depends on finding both C and M. Statement III provides C directly as Rs. 28,000. Statement I gives the equation 0.125M = 3750, allowing the calculation of M. Statement II gives the equation 0.875M + 1750 = C, providing the ratio of M to C. Therefore, any one of the statements is redundant because only two are needed to establish the values, and any one of them can be dispensed with. The result is any one of them.
