One mole of ammonia was completely absorbed in one litre solution each of (a) 1 M HCI, (b) 1 M `CH_3COOH` and (c) 1 M `H_2SO_4` at 298 K.
The decreasing order for the pH of the resulting solution is (Given `K_(b) (NH_3) = 4.74`)

A

`2 gt 3 gt 1`

B

`1 gt 2 gt 3`

C

`2 gt 1 gt 3`

D

`3 gt 2 gt 1`
