Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Because group 1 metals are so strongly basic, they (except lithium) also form solid bicarbonates. No other metals form solid bicarbonates.

Lithium carbonate is not so stable to heat. Its hydrogen carbonate does not exist as a solid. Although $N H_{4} H C O_{3}$ also exists as a solid.

The crystal structures of $N a H C O_{3}$ and $K H C O_{3}$ both show hydrogen bonding but are different.

Therefore, the correct option is (B).
