D Correct answer
Explanation

Bleeding takes place through injured organs of the plant. It usually describes fluid oozing from injured plant parts. Transpiration describes the loss of water in vapour form and helps in cooling of leaf surface as well as the movement of mineral ions in transpiration stream. Transpiration is primarily responsible for uptake of water circulating in plant's xylem vessels and tracheids.

A Correct answer
Explanation

Oozing out of water drops from injured edges or tips in plants is called bleeding. Bleeding usually develops because of the pressure of sap inside of the tissues which conducts water and sugars around the plant. If any positive pressure exist in the xylem due to any cut or opening results in the exudation or bleeding of the solution from the trachery elements.

So, the correct answer is option A.

A Correct answer
Explanation

When water oozes out from the pores of the plants known as Hydathodes then it is known as Guttation.

When water vapour is released from the stomata then the process is known as transpiration .
When the water oozes out from injured leaf edges then it is known as bleeding. 
So the correct answer is 'Bleeding'.
