Ans. C Enlarging the gingival sulcus and control of hemorrhage 

The use of electrosurgery has been recommended for enlargement of the gingival sulcus and control of hemorrhage to facilitate impression making. Strictly speaking, electrosurgery cannot stop bleeding once it starts. If hemorrhage occurs, it first must be controlled by pressure or chemicals, and then the vessels can be sealed with a coagulating ball electrode.
