Solution

The correct option is B $H_{2} S O_{4}$
Strong electrolytes find application in the working of the cell due to their ability to undergo complete dissociation. Out of the given option, only $H_{2} S O_{4}$ is a strong electrolyte, while $C H_{3} C O O H, N H_{4} O H,$ and $C u (O H)_{2}$ are weak electrolytes.
