(c)

Assertion is true but Reason is false.

Explanation
The join, in which columns are compared for equality, is called Equi-join. Join queries in SQL can produce combined rows based on various conditions, not just equality comparisons. For example, join conditions can involve inequality comparisons (<, >, <=, >=), as well as other logical operators and functions.
