first defined
last defined
foreign key
primary key
Answer is Right!
Answer is Wrong!
The correct answer is: C. foreign key
A foreign key is a field in one table that refers to the primary key of another table. It is used to establish a relationship between the two tables. In a junction table, the foreign key field consists of the foreign key from both the linked tables. This is because the junction table is used to link the two tables together.
The other options are incorrect because:
- Option A is incorrect because the order in which the fields are defined does not matter.
- Option B is incorrect because the order in which the fields are defined does not matter.
- Option D is incorrect because the primary key is a field in a table that uniquely identifies each row in the table. It is not used to establish a relationship between two tables.
