Every variable has both a value and . . . . . . . .

Unique address
Value
Name
Relative address

The correct answer is: A. Unique address

A variable is a location in memory that can store a value. Every variable has a unique address that is used to access the value stored in the variable. The address of a variable is determined by the compiler when the program is compiled.

The other options are incorrect because:

  • A value is the data that is stored in a variable.
  • A name is a label that is used to identify a variable.
  • A relative address is an address that is relative to the address of another variable.
