Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
As the magnetic monopole does not exist, thus magnetic field lines form closed loops.So the number of field lines going out through the closed surface is equal to number of field lines coming in. Hence magnetic flux linked with a closed surface is always zero.
