B Correct answer
Explanation

A hypsometer is an instrument used to measure altitude or height above sea level. It works by measuring the boiling point of water, which decreases with increasing altitude due to lower atmospheric pressure. Hygrometers measure humidity, voltmeters measure electrical potential difference, and amperemeters measure electric current.
