Answer:

Correct Answer: A

Solution:

Succulent leaves are fleshy or swollen.

They store water, mucilage or food materials.

Succulent leaves occur in plains of saline and xerophytic habitats, e.g., Aloe, Agave, Bryophyllum, Portulaca.

These plants possess a water tissue, which consists of turgescent parenchyma cells with delicate cellulose walls, thin peripheral layers of cytoplasm and few or no chloroplasts.
