$\text{Option B...........}$

#### Explanation:

Sodium carbonate gives a basic solution, according to the equilibrium......

$C {O}_{3}^{2 -} + {H}_{2} O \left(l\right) r i g h t \le f t h a r p \infty n s H C {O}_{3}^{-} + H {O}^{-}$

$p {K}_{b} = 3.57$..........

Sodium chloride is does not cause hydrolysis; on the other hand, sodium bisulfate is a moderately strong acid......

$H S {O}_{4}^{-} + {H}_{2} O \left(l\right) r i g h t \le f t h a r p \infty n s S {O}_{4}^{2 -} + {H}_{3} {O}^{+}$
