Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Elemental sodium is a good reducing agent, as it belongs to group-I and elements of group-I have one electron in their valence sheet. So, they loose $1$ electron readily to attain noble gas configuration, hence undergoing oxidation (i.e loss of electron) and acting as a good reducing agent.
