Answer:

( A ).Assertion and reason both are correct statements and reason is correct explanation for

Explanation:

NH4OH is a weak base it does not ionizes completely, while NH4Cl is a strong electrolyte, It decomposes completely. Due to the presence of NH4+ in NH4Cl, It suppresses the ionisation of weak base NH4OH to decrease the OH- ion concentration so that higher group cations will not get precipitated.
