Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Sclerenchyma cells do not have plasmodesmata as their cell walls are heavily lignified. Sclerenchyma provides structural support to a plant. Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. Their walls consist of cellulose, hemicellulose and lignin. Sclerenchyma cells are the principal supporting cells in plant tissues that have ceased elongation.
Thus, the correct answer is option A.
