Solution

The correct option is D $N a H {C O}_{3}$
On heating ${N a H C O}_{3}$ decomposes as $\to$

${2 N a H C O}_{3} \to {N a}_{2} {C O}_{3} + {C O}_{2} + H_{2} O$

${N a}_{2} {C O}_{3}$ is very stable and on heating to very high temperature it changes into molten ${N a}_{2} {C O}_{3}$ , but does not decomposes.
Hence, the correct option is B
