A Correct answer
Explanation

A foreign key table is the table that contains the foreign key field being validated. Here, T1 contains field t1-fielda which needs to be validated against the check table T2's field t2-fielda. Therefore T1 is the foreign key table (dependent table) and T2 is the check table.
