What will be the output of this code?

class Box:
    def __init__(self):
        self.size = 5

    def enlarge(self):
        self.size += 3

b = Box()
b.enlarge()

A5

B8

C3

DError

Step-by-Step Solution

Solution:

Step 1: Initial attribute value
The Box object b starts with size = 5 from __init__.
Step 2: Method enlarge changes size
Calling b.enlarge() adds 3 to size, so size becomes 5 + 3 = 8.
Final Answer:
8 -> Option B
Quick Check:
5 + 3 = 8 [OK]

Quick Trick: Add changes inside method to attribute value [OK]
