Answer:
The attributes of a table is said to be dependent on each other when an attribute of a table uniquely identifies another attribute of the same table. For example: Suppose we have a student table with attributes: Stu_Id, Stu_Name, Stu_Age.

An attribute is fully functional dependent on another attribute, if it is Functionally Dependent on that attribute and not on any of its proper subset. For example, an attribute Q is fully functional dependent on another attribute P, if it is Functionally Dependent on P and not on any of the proper subset of P.
