Solution

The correct option is D

Both assertion and reason are true and the reason is the correct explanation for the assertion.


The metallic character increases as we go down the group since the size of atoms increases which results in the decrease of ionisation energy. So it is easy for an element with low ionisation energy to lose or donate electrons.
