Assertion and Reason both are correct but Reason is not the correct explanation of Assertion.

Vedclass · Answer

(B) The influx of ions into the inner space of cells (cytoplasm) is an active process because it requires energy to move ions against their electrochemical gradient across the plasma membrane.$R$ is a correct statement because ions are indeed available for free exchange in the free space (apoplast) of the cell wall.However,the availability of ions in the free space does not explain why the movement into the inner space is an active process. Therefore,$R$ is not the correct explanation for $A$.

$A$: Influx of ions into the inner space of cells is an active process.
$R$: Ions are available for free exchange in the free space.
