Final answer:
The answer to the problem has three significant figures.
Step-by-step explanation:
To determine the number of significant figures in the answer, we need to identify the number with the fewest significant figures in the calculation. In the given problem, (9.992 × 3.200) + 0.610, the number with the fewest significant figures is 0.610, which has three significant figures. Therefore, the answer to the problem will also have three significant figures.
The correct answer is option C) three.
