Plants release excess water through a process called:

Correct option is B

The correct answer is (b) transpiration.
Explanation:

Transpiration is the process through which plants release excess water vapor into the atmosphere, primarily through small openings on the leaves called stomata. This process is essential for several reasons:
· It helps in cooling the plant.
· It aids in the uptake of nutrients and water from the soil.
· It maintains the flow of water and minerals through the plant.
Other Options:

• Translocation refers to the movement of water, nutrients, and food (mainly sugars) within the plant, particularly through the phloem.
  
• Transportation is a broader term and can refer to the movement of substances within a plant or organism, but it’s not specific to water loss.
  
• Evaporation is the process by which water changes from a liquid to a gas and can happen from any surface, not just plants.
