b) child .
The child table in an Entity-Relationship Diagram (ERD) can generally be identified by the presence of a foreign key constraint. A foreign key is a field (or collection of fields) in one table that uniquely identifies a row of another table or the same table. In this context, the foreign key in the child table refers to the primary key of the parent table to define the relationship between the two.
