Which of the following plots will obtained for a conductomeric titration of strong acid against a weak base?

Options

A.
B.
C.
D.

Answer

C

Explanation

Take an example
`underset(SA)(H^(+)Cl^(-))+underset(WB)(NH_(4)OH)rarrunderset("salt")(NH_(4)Cl)+H_(2)O`
on tiration `H^(+)` is replace by `NH_(4)^(+)` which have less conductance so conductance decreased upto equivalence point and after that weak base addition can't contribute more considerable conductance with respect to present salt `(NH_(4)Cl)` in solution
