Consider the table given below :
Salesperson

Orders
| Orders | SalespersonID | Amount |
| 10 | 2 | 54000 |
| 20 | 7 | 18000 |
(i) The column in the "Salesperson"
table is the ................. KEY. The SalespersonId column in the "Orders" table is a .................. KEY.
(ii) Can the 'Salespersonld' be set as the primary key in table 'Orders'. Give reason.
