Answer

B

Explanation

The pattern across the columns is:

  • Column 1: (21−8)×9=13×9=117(21 - 8) \times 9 = 13 \times 9 = 117
  • Column 2: (34−9)×8=25×8=200(34 - 9) \times 8 = 25 \times 8 = 200
  • Column 3: (?−13)×5=110  ⟹  ?−13=22  ⟹  ?=35(? - 13) \times 5 = 110 \implies ? - 13 = 22 \implies ? = 35.
