Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Calcium is absorbed from the soil without spending energy (passive). In the plant, it moves to different plants through the xylem, along with water. From the soil, it is absorbed in the form of calcium ions ( $C a^{2 +}$ ).
Calcium is essential for the plant in metabolic processes of other nutrients uptake. It promotes proper plant cell elongation and it is required by meristematic and differentiating tissues.
So, the correct answer is option B.
