b. 152 pounds
c. 200 pounds
d. 152.127 pounds

Explanation:

Step1: Understand the scale's precision

The scale measures to the nearest 0.1 pounds, so the reported weight should have one decimal place (to the tenths place).

Step2: Analyze each option

• Option A: 152.2 pounds has one decimal place, matching the scale's precision.
• Option B: 152 pounds has no decimal places, less precise than the scale's capability.
• Option C: 200 pounds has no decimal places, less precise.
• Option D: 152.127 pounds has three decimal places, more precise than the scale (which only goes to the nearest 0.1, so tenths place), so this over - reports precision.
