• B. 0°C
• C. 32°C
• D. 25°C

Answer: (B)

Verified step by step guidance

1. Understand that the thermometer reading is given directly as 0°C, which means the temperature it shows is exactly 0 degrees Celsius.
2. Recall that the Celsius scale is defined such that 0°C corresponds to the freezing point of water under standard atmospheric conditions.
3. Recognize that the thermometer reading of 0°C does not require any conversion or adjustment since it is already expressed in Celsius.
4. Compare the given options to the thermometer reading: since the thermometer shows 0°C, the correct temperature in Celsius is 0°C.
5. Conclude that the thermometer reading of 0°C corresponds exactly to 0 degrees Celsius, confirming the correct answer.
