  2. B. Thermometer

Correct Answer

Option D — Sphygmomanometer

Detailed Solution & Explanation

A sphygmomanometer is the instrument used to measure blood pressure in the human body. It consists of an inflatable cuff (wrapped around the upper arm) connected to a pressure gauge (mercury manometer or aneroid gauge). Blood pressure is recorded as two numbers: systolic pressure (when the heart beats) over diastolic pressure (when the heart rests), measured in mmHg. A stethoscope is used to hear heart/lung sounds, an endoscope examines internal organs, and a thermometer measures body temperature.
