Solution

The correct option is C Assertion is incorrect but Reason is correct
Sodium carbonate is a very stable carbonate,resisting decomposition upto a very high temperature,often till its melting temperature.
$N a (H C O_{3}) \to N a_{2} C O_{3} + C O_{2} + H_{2} O$
Sodium carbonate do not decompose.
