Solution

The correct option is E Assertion is correct but Reason is incorrect
Sulfa drug contains a sulfonamide group which $S O_{2} N H_{2}$ group.
Salvarsan also called arsphenamine does not contain a sulfonamide group as shown in the figure.
Thus, the assertion is correct but Reason is incorrect.

Hence, the correct option is $D$
