Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Element X has electronic configuration 2, 8, 18, 8, 1. By losing one electron X will have stable octet.

So it has tendency to loose one electron (oxidise) and because of this tendency, it will acts as reducing agent.
