Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
The endodermis is a single layer of cells that borders the cortex of a root.
These cells are impregnated with hydrophobic substances (Casparian Strip) to restrict the flow of water to the inside.
The endodermis helps regulate the movement of ions into and out of the vascular system by an active process.
Hence, the movement of ions from endodermis to non-living xylem elements is an active process as It requires the involvement of metabolic energy, which comes from respiration.
So, the correct answer is 'Both assertion and reason are correct. And the reason is the correct explanation to the assertion'.
