DError: Cannot assign function to variable

Step-by-Step Solution

Solution:

Step 1: Assign function to variable
The variable 'operation' stores the function 'add' without calling it.
Step 2: Call the function via variable
Calling 'operation(3, 4)' executes 'add(3, 4)' which returns 7.
Final Answer:
7 -> Option C
Quick Check:
Function call via variable = 7 [OK]

Quick Trick: Calling function variable runs original function [OK]
