B Correct answer
Explanation

Step-by-step: 103.1% of 6401 ≈ 1.031 × 6400 = 6598.4. (3/7)% of 6300 ≈ 0.0043 × 6300 = 27.09. So 6598.4 - 27.09 + 12 = 6583.31. Refined calculation: 1.031×6401=6595.43, 0.0043×6300=27.09, 6595.43-27.09+12=6580.34. The closest option is 6557 (option B). The approximation is reasonable.
