Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
In case of the electric field of an electric dipole, the electric lines of force originate from positive charge and, end at negative charge. Since, isolated magnetic lines are closed continuous loops extending throughout the body of magnet, hence they form endless curves.
