Solution

The correct option is C C6H5NHC6H5
In the compound mentioned in part C, the lone pair of nitrogen is in conjugation with both the phenyl rings.

So, they are greatly dispersed and are not available for donation.

As a result, the compound C is least basic.

Least basic means least Kb value and least Kb value means highest pKb value.

Option C is correct.
