Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Plasmodesmata are the intercellular connection between the two cells. These are formed when a portion of the endoplasmic reticulum are trapped between fusing vesicles during the cell wall formation between the newly formed daughter cell. It is the cytoplasmic thread like junction between two adjacent cell for communication.
Thus, the correct answer is option B.
