Solution

The correct option is A It give positive charge to the cell wall
Calcium Chloride imparts a positive charge to the cell wall. Since DNA is negatively charged molecule, the positive charge on the cell wall imparted by calcium chloride helps the DNA to get attracted towards the cell, and hence ensures a higher efficiency of successful transformants.
