Correct Answer: D

Rationale: To divide 40.3 by 4.8, we perform the division operation as follows: 40.3 ÷ 4.8 = 8.39583... Rounded to one decimal place, the result is 8.4, which is the correct answer (Choice D). Choice A (0.084) is incorrect as it is the result of dividing 40.3 by 480. Choice B (84) is incorrect as it is the result of multiplying 40.3 by 4.8. Choice C (0.84) is incorrect as it is close to the correct answer but not the precise result of the division.

Correct Answer: B
