Answer

Correct option: B.
Both $A$ and $R$ are true but $R$ is not the correct explanation of the assertion.
The plants store some of the waste products in their body parts. For example some of the waste products are collected in the leaves, bark and fruits of the plants. The plants get rid of these wastes by shedding of leaves, peeling of bark and fruits. Some of the plant wastes get stored in the fruits of the plant in the form of solid bodies called raphides. These are removed when the fruits, get detached from the plant. For example, the 'Yam' fruit has needle shaped raphides on its surface.
