Answer 2

Option(b) a foreign key combined with a primary key creates a parent-child relationship.

• When two tables want to link then one column is defined as a foreign key.
• The value in that column is the same as the other table's column values.
• Whereas the primary key is for identifying each row in a table.
• When the primary and foreign keys add together then it will result in a relationship between parent and child.
