Correct answer: C
Answer: 0
Reasoning:
Use the alphabetical positions of letters (A = 1, B = 2, …). In each row:
Left number = sum of letters with even alphabetical positions.
Right number = sum of letters with odd alphabetical positions.
Check each row to see the pattern:
F K M → F = 6 (even), K = 11 (odd), M = 13 (odd). Even sum = 6 → left = 6. Odd sum = 11 + 13 = 24 → right = 24.
L U C → L = 12 (even), U = 21 (odd), C = 3 (odd). Even sum = 12 → left = 12. Odd sum = 21 + 3 = 24 → right = 24.
I R B → I = 9 (odd), R = 18 (even), B = 2 (even). Even sum = 18 + 2 = 20 → left = 20. Odd sum = 9 → right = 9.
D G Q → D = 4 (even), G = 7 (odd), Q = 17 (odd). Even sum = 4 → left = 4. Odd sum = 7 + 17 = 24 → right = 24.
P J H → P = 16 (even), J = 10 (even), H = 8 (even). Even sum = 16 + 10 + 8 = 34 → left = 34. Odd sum = 0 (no odd-valued letters) → right = 0.
Therefore the number that replaces the question mark is 0.
