AA thermometer
BA galvanometer
CA manometer
DA voltmeter
Answer & Solution
Correct answer: A. A thermometer
1. Temperature is literally defined as what is measured on a thermometer.
2. A galvanometer measures small electric currents, not temperature.
3. A manometer measures fluid pressure, not temperature.
4. A voltmeter measures voltage, not temperature, so a thermometer is the correct instrument.
