Answer #1

A primary key is a(n) (candidate) key chosen to be the primary means by which rows of a table are uniquely identified

Explanation:-

All primary keys are definitely candidate keys . Candidate key is used to uniquely identify the records of a table.

There will be so many candidate keys in one table,but we choose only one candidate key as the primary key for the table

primary key should be one in a table.

so,the answer is :- candidate key for the given que (if a(n) is primary key then it must be chosen from candidate keys)
