Answer: (A)

Verified step by step guidance

1. Understand the process of transpiration: Transpiration is the process by which water is absorbed by plant roots, moves through plants, and is released as water vapor through small openings called stomata.
2. Identify the location of stomata: Stomata are primarily located on the leaves of plants. These are tiny openings that facilitate gas exchange and water vapor release.
3. Consider the role of leaves: Leaves are the main site for photosynthesis and gas exchange, making them the primary location for transpiration due to the presence of numerous stomata.
4. Evaluate other plant parts: While roots absorb water and stems transport it, these parts do not have stomata and are not the primary sites for transpiration.
5. Conclude that leaves are the primary site: Based on the presence of stomata and their role in gas exchange, transpiration primarily occurs in the leaves of the plant.
