B Correct answer
Explanation

Kashish's investment: 2600 × 7 + (2600+600) × 5 = 18200 + 16000 = 34200. Sheena's investment: 2400 × 7 + (2400+800) × 5 = 16800 + 16000 = 32800. Ratio of investments = 34200:32800 = 171:164. After 33% donation, 67% remains. If total profit = P, difference = P × (67/100) × (171-164)/(171+164) = P × 0.67 × 7/335 = 350. Solving: P = 350 × 335/(0.67 × 7) = 25000.
