Thermometer sensitivity vs. range comparison

Steps:

• Sensitivity measures the smallest temperature change detectable, often tied to the liquid's expansion coefficient and capillary bore size.
• Range is the minimum to maximum temperature the thermometer can measure reliably.
• Without descriptions or data for thermometers P, Q, R, S, direct comparison is impossible.
• Not enough information to determine which has greatest sensitivity or range.

Why C is correct:

• Cannot confirm; lacks supporting details like expansion coefficients or temperature spans.

Why the others are wrong:

• A: No evidence P has highest sensitivity or R highest range.
• B: No evidence Q has highest sensitivity or S highest range.
• D: Duplicate of B; same lack of evidence.

Final answer: Not enough information.
