Answer 2

The answer is Option 2) KCl

• Hydrolysis occurs due to there being a weak base or weak acid present in the solution
• $NH_4^+$ is weak and hence it will undergo hydrolysis.
• Both $K^+$ and $Cl^-$ are strong and hence it won't undergo hydrolysis.
• $CH_3COO^+$ is weak and hence it will undergo hydrolysis.
• $CO_3^{2-}$ is weak and hence it will undergo hydrolysis.

Therefore KCl won't undergo hydrolysis.
