Multiple choiceEasychapter-1-curatedpremiumcore-javascope-and-reassignment
Answer and explanation
Correct answer
C. The local variable is updated only within the method.
Why
Local variables are confined to the method in which they are defined. When a local variable is reassigned, the change only affects that variable within the method. It does not impact the same variable name elsewhere in the program.
