You administer a Microsoft SQL Server 2012 database.
The database contains a table named Employee. Part of the Employee table is shown in the exhibit. (Click the Exhibit button.)
Unless stated above, no columns in the Employee table reference other tables.
Confidential information about the employees is stored in a separate table named EmployeeData. One record exists within EmployeeData for each record in the
Employee table.
You need to assign the appropriate constraints and table properties to ensure data integrity and visibility.
On which column in the Employee table should you create a Primary Key constraint for this table?
A.
DateHired
B.
Departments
C.
EmployeeID
D.
EmployeeNum
E.
FirstName
F.
JobTitle
G.
LastName
H.
MiddleName
I.
ReportsToID
I think it is I->ReportsToID.
The same Question as 70-461 (v.4) Question Nr. 47.

No it is C.
https://www.w3schools.com/sql/sql_primarykey.asp
On ReportsToId you must create foreign key, that point to EmployeeID, which must be the primary key of the table.
If you set primary key on ReportsToId you will have only one pare of boss-employee, because primary key is unique for the table.
