CCannot add key and value directly

DNo error, code runs fine

Step-by-Step Solution

Solution:

Step 1: Check for destructuring syntax
The for loop uses for (key, value in map) which lacks parentheses around key, value.
Step 2: Understand correct syntax
Kotlin requires parentheses for destructuring pairs: for ((key, value) in map). Without them, it's a syntax error.
Final Answer:
Missing parentheses around key and value in for loop -> Option A
Quick Check:
Parentheses required for destructuring [OK]

Quick Trick: Always use parentheses for destructuring in for loops [OK]
