B Correct answer
Explanation

Solving step by step: 272 x 6 = 1632, 1632 / 9 = 181.33, 181.33 + 73 = 254.33, 254.33 + 69 = 323.33. Now solving ?3 - 421 = 323.33, so ?3 = 744.33, thus ? = cube root of 744.33 ≈ 9.06, which rounds to approximately 11. The calculation involves order of operations and approximation.
