Afor ((index, value) in items.withIndex()) { /* code */ }

Bfor (index, value in items) { /* code */ }

Cfor (index; value in items.withIndex()) { /* code */ }

Kotlin allows destructuring pairs using parentheses in the for loop header, like for ((index, value) in ...).
Step 2: Match syntax with withIndex()
The correct syntax uses items.withIndex() and destructures the pair into index and value.
Final Answer:
for ((index, value) in items.withIndex()) { /* code */ } -> Option A
Quick Check:
Destructure pairs with (index, value) [OK]

Quick Trick: Use parentheses to destructure pairs in for loop [OK]
