Answer

Explanation:

Step1: Understand precision concept

Precision refers to how close the measurements are to each other.

Step2: Analyze each option

For option A, values are 24.5°C, 20°C, 21°C with larger differences. For option B, values 12.0°C, 18.1°C, 14.2°C have significant differences. For option C, values 18°C, 16°C, 20.0°C also have noticeable differences. For option D, values 15.6°C, 15.6°C, 15.9°C are very close to each other.

Answer:

D. 25 m depth: 15.6°C, 15.6°C, 15.9°C
