B Correct answer
Explanation

The pattern is n×(n+1) - for 8: 8×9=72, but this gives 72, not 32. Alternative: n² - for 8: 64, not 32. Alternative: 8×4=32 works. For 10: 10×5=50. The pattern n×(n-?+1) doesn't work. Testing n×(constant): 8×4=32, 10×5=50. This suggests the multiplier equals (first number ÷ 2): for 8, multiplier is 4; for 10, multiplier is 5. So 10×5=50, option B.
