• B. Xylem sap
• C. Guttation fluid
• D. Only water

Answer 1

The correct option is A Phloem sap

Phloem sap contains carbohydrates, in which sucrose is the main component, produced by photosynthesis. It contains living cells. Phloem sap movement is bidirectional in nature, i.e., from where the carbohydrates are formed to where they are used. Phloem originates from meristemic cells in the vascular cambium. It helps in sending signals throughout vascular plants.

So, the correct option is 'Phloem sap'.
