• C. Thermometer
• D. Ventilator

Answer 1

The correct option is A Sphygmomanometer

A sphygmomanometer is an instrument used to measure blood pressure.
$\bullet$ Blood pressure is the pressure exerted by blood on arterial walls.
$\bullet$ Systole- the phase when the heart pumps blood out into the aorta.
$\bullet$ Diastole - the resting period when the heart refills with blood.
During each heartbeat, blood pressure is raised to the systolic level and between beats, it drops to the diastolic level.
