  1. At constant temperature, the rate of transpiration will be higher at
    1. Sea level
    2. 1 km below sea level
    3. 1 km above sea level
    4. 1.5 km above sea level
Correct Option: D

The rate of transpiration is inversely proportional to the atmospheric pressure. Increased height above the sea level lowers the atmospheric pressure and increases the rate of evaporation.
