Solution

The correct option is A $C H_{3} C O O H + N a O H$
In a displacement reaction hydrogen gas can be liberated. This can be explained as, Those elements which are above H in reactivity series can displace H from its solution.
Here $C H_{3} C O O H + N a O H$ is displacement reaction
so this reaction is not liberated hydrogen gas

Hence C is correct option
