Which instrument measures humidity?

Humidity is the amount of water vapor in the air, and you measure it with a hygrometer. The question is asking what quantity is being measured, and among the options, humidity directly denotes that parameter, contrasting with temperature, pressure, or wind speed, which are measured by their own specific instruments (thermometer, barometer, anemometer). So humidity is the best match.
