B Correct answer
Explanation

Following order of operations: 256.5 × 54 = 13851, then 13851 ÷ 81 ≈ 171, then 171 + 72 = 243, finally 243 ÷ 89.89 ≈ 2.703. The approximation to one decimal place gives 2.7. The key is working left to right with multiplication and division before addition, then approximating the final division.
