Solution

The correct option is B KOH
The respirometer is a glass apparatus which is used to measure the RQ of the different respiratory substrate. KOH solution absorbs $C O_{2}$ released by germinating seeds in the respirometer and vacuum is created. The created vacuum raises the $H g$ level in the tube which provides the estimation volume of $C O_{2}$ released during respiration.
