Solution

Zinc sulfate( $Z n S O_{4}$ ) is a strong acid or strong electrolyte.
So it can easily react with strong alkali to give a gelatinous white precipitate and is due to the formation of Zinc hydroxide( $Zn {(OH)}_{2}$ )
Let us take an example with Potassium hydroxide( $K O H$ )
The reaction is,
$Z n S O_{4} + 2 K O H \to Z n {(O H)}_{2} (Z i n c h y d r o x i d e) + K_{2} S O_{4}$
The solution C or strong alkali which gives gelatinous white precipitate by reacting with Zinc sulfate( ${ZnSO}_{4}$ ) and will disappear when excess is added.
