A trivial functional dependency is a database dependency that occurs when describing a functional dependency of an attribute or of a collection of attributes that includes the original attribute.
So, Option c is correct answer.

In Trivial Functional Dependency, a dependent is always a subset of the determinant.
i.e. If X → Y and Y is the subset of X, then it is called trivial functional dependency.
so option A is correct.
i.e. If X → Y and Y is the subset of X, then it is called trivial functional dependency.
so option A is correct.
