[Solved] Identify the error in this Ruby code: a = [1, 2, 3] b = ["x", "y"] result = a.zip b puts result — Ans: No error; code runs and prints zipped array | Ruby

Ruby - Enumerable and Collection Processing

Identify the error in this Ruby code:

a = [1, 2, 3]
b = ["x", "y"]
result = a.zip b
puts result

AMissing parentheses in zip call causes syntax error

BNo error; code runs and prints zipped array

CUsing puts on array prints object id instead of content

Dzip method requires block, so code fails

Step-by-Step Solution

Solution:

Step 1: Check syntax of zip call without parentheses
Ruby allows method calls without parentheses if arguments are present.
Step 2: Check output of puts on array
puts prints each element on a new line, so it works fine here.
Final Answer:
No error; code runs and prints zipped array -> Option B
Quick Check:
zip without parentheses is valid = no error [OK]

Quick Trick: Parentheses optional for single method argument [OK]
