Why does a child class need to call super().__init__() when it defines its own __init__ method?

ATo ensure the parent class is properly initialized

BTo override the parent class completely

CTo prevent the child class from having attributes

DIt is optional and has no effect

Step-by-Step Solution

Solution:

Step 1: Understand constructor chaining
If a child defines __init__, it replaces parent's __init__, so parent's initialization won't run unless called explicitly.
Step 2: Purpose of super().__init__()
Calling super().__init__() runs parent's __init__, setting up inherited attributes correctly.
Final Answer:
To ensure the parent class is properly initialized -> Option A
Quick Check:
super().__init__() runs parent's constructor [OK]

Quick Trick: Call super().__init__() to initialize parent attributes [OK]
