The correct answer is: A. The value in the Const statement.
A named constant is a variable that has a fixed value. It is declared using the Const statement. The value of a named constant cannot be changed during the execution of the program.
To change the value of a named constant, you need to change the value in the Const statement. For example, if you have a named constant called pi that is initialized to the value 3.14, you can change the value of pi to 4.2 by changing the statement Const pi = 3.14 to Const pi = 4.2.
The other options are incorrect because they do not change the value of the named constant. Option B is incorrect because the value of the variable is not changed in the Const statement. Option C is incorrect because the value of the variable is not changed anywhere in the program. Option D is incorrect because the value of the variable is not changed in one of the procedures in the program.
