• C. Sphygmomanometer
• D. EEG

Answer 1

The Correct Option is C

Step 1: Understand what is being measured. Blood pressure refers to the force exerted by circulating blood on the walls of arteries.
Step 2: Identify the function of each instrument.
ECG (Electrocardiogram) — records the electrical activity of the heart.
Stethoscope — used to listen to heartbeats, lung sounds, and other internal sounds.
Sphygmomanometer — used to measure blood pressure.
EEG (Electroencephalogram) — records electrical activity of the brain.
Step 3: Select the correct instrument. Only the sphygmomanometer is designed specifically to measure blood pressure.
Hence, the correct answer is \[ \boxed{\text{Sphygmomanometer}} \]
