Solution

The correct option is C Assertion is correct but Reason is incorrect.

Equivalent weight of a base $= \frac{M o l e c u l a r w e i g h t}{A c i d i t y}$ .

Acidity is the number of replaceable hydroxyl ions in one molecule of the base.
So Assertion is correct but Reason is incorrect statement.
