Solution

The correct option is A $3 m M H C O O H (K_{a} = 6 \times 10^{4})$
Addition of $C H_{3} C O O H$ and $H C l$ will change the $p H$ . Adding the $C H_{3} C O O N a$ will form a buffer solution and hence change the $p H$ . Here, addition of $H C O O H$ will not change degree of dissociation or $p H$ of the solution.
