When a value is converted from one data type to another and can store numbers with greater precision, the value is said to be . . . . . . . .

The correct answer is C. Promoted.

When a value is converted from one data type to another and can store numbers with greater precision, the value is said to be promoted. This is because the new data type has a larger range of values that can be stored, and therefore the value can be stored more precisely.

For example, if a value of type int is promoted to type long, the value can be stored with greater precision because the long data type has a larger range of values that can be stored.

• Option A, Imported, is incorrect because it refers to the process of bringing data into a program from an external source.
• Option B, Exported, is incorrect because it refers to the process of sending data out of a program to an external source.
