Which of the following best describes the lifetime of a local variable stored in stack memory?

AIt exists permanently in the program

BIt exists until the program terminates

CIt exists until the object is garbage collected

DIt exists as long as the method is executing

Step-by-Step Solution

Solution:

Step 1: Identify local variable scope
Local variables live only during the method execution where they are declared.
Step 2: Understand stack frame lifetime
When the method finishes, its stack frame is removed, and local variables are destroyed.
Final Answer:
It exists as long as the method is executing -> Option D
Quick Check:
Local variable lifetime = method execution time [OK]

Quick Trick: Local variables vanish when method ends [OK]
