Ruby - Metaprogramming Fundamentals

Identify the error in this code snippet using OpenStruct:

require 'ostruct'
person = OpenStruct.new
person[:name] = "Bob"
puts person.name

Aperson.name is undefined because name was never set

BMissing parentheses in OpenStruct.new

CCannot use puts with OpenStruct properties

DOpenStruct does not support []= for setting properties

Step-by-Step Solution

Solution:

Step 1: Check how properties are set in OpenStruct
OpenStruct properties are set by dot notation (e.g., person.name = "Bob"), not by bracket notation.
Step 2: Analyze the code behavior
Using person[:name] = "Bob" tries to use []= method which OpenStruct does not support, causing an error.
Final Answer:
OpenStruct does not support []= for setting properties -> Option D
Quick Check:
Use dot notation, not []= [OK]

Quick Trick: Set properties with dot, not brackets [OK]
