Why might the __del__ method not be called for some Python objects?

ABecause of circular references preventing garbage collection

BBecause __del__ is called immediately on object creation

CBecause __del__ replaces __init__

DBecause Python does not support destructors

Step-by-Step Solution

Solution:

Step 1: Understand __del__ and garbage collection
__del__ is called when an object is garbage collected, but circular references can prevent collection.
Step 2: Identify why __del__ might not run
If objects reference each other in a cycle, Python's garbage collector may not immediately collect them, delaying or skipping __del__ calls.
Final Answer:
Because of circular references preventing garbage collection -> Option A
Quick Check:
Circular refs block __del__ = May not be called [OK]

Quick Trick: Circular references can delay or block __del__ calls [OK]
