Ruby - Loops and Iteration

Which of the following is the correct syntax for iterating over an array arr in Ruby?

Afor i in arr puts i end

Barr.each { |item| puts item }

Carr.loop { |item| puts item }

Darr.iterate do |i| puts i end

Step-by-Step Solution

Solution:

Step 1: Identify valid Ruby iterator syntax
The method each is the standard iterator for collections in Ruby.
Step 2: Check each option
arr.each { |item| puts item } uses arr.each { |item| puts item }, which is correct syntax. The for loop "for i in arr puts i end" has invalid syntax (missing 'do'), options C and D use invalid method names.
Final Answer:
arr.each { |item| puts item } -> Option B
Quick Check:
Correct iterator syntax = A [OK]

Quick Trick: Look for each with block syntax for iteration [OK]
