C Correct answer
Explanation

Calculate LHS: 13 × 15.5 = 201.5, then 201.5 + 53.774 = 255.274, then 255.274 - 321.3 = -66.026. So -66.026 = ? - 131.05, therefore ? = 131.05 - 66.026 = 65.024 ≈ 65. Option C is correct. Options A (60), B (70), and D (80) are calculation errors from misplacing decimal points or wrong operations.
