Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Alkali metals are the chemical elements found in Group 1 of the periodic table and have $n s^{1}$ configuration, so they have high tendency to loose electron and have complete octet configuration.
Due to this tendency alkali metals are good reducing agents.
