Solution

The correct option is B Assertion and Reason, both are true.
Sodium Metal has an electronic configuration of 2, 8, 1. The outermost shell has an electron which it can lose easily hence, it is reactive. Sodium Ions have a configuration of 2, 8, which is stable. Hence it is not reactive further.
