consider the following statement A and B , and select the correct choice A: Repulsion is a sure test of magnetism. (B) : Magnetic induction precedes attration.

Only A is true

Only B is true

Both are true

Both are false

Assertion :Repulsion, is the surest test of magnetism. Reason : Like poles of magnets repel each other.

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If assertion is false but reason is true.

A sure test of electrification is
