Which of the following Kotlin code snippets correctly uses forEach to print each element of the list items?

Aitems.forEach { println(it) }

Bitems.forEach(println(it))

Citems.forEach -> println(it)

Ditems.forEach { print(it.length) }

Step-by-Step Solution

Solution:

Step 1: Syntax of forEach
The correct syntax uses a lambda expression: forEach { element -> action } or forEach { action(it) }.
Step 2: Analyze options
items.forEach { println(it) } correctly prints each element. items.forEach(println(it)) is invalid syntax. items.forEach -> println(it) uses incorrect arrow syntax. items.forEach { print(it.length) } prints length, not the element.
Final Answer:
items.forEach { println(it) } -> Option A
Quick Check:
Lambda inside forEach must be enclosed in braces [OK]

Quick Trick: Use braces and lambda to print each element [OK]
