Ruby - Classes and Objects

Identify the error in this Ruby class:

class Car
  attr_reader :model
  def initialize(model)
    @model = model
  end
  def model=(value)
    @model = value
  end
end

car = Car.new('Sedan')
car.model = 'SUV'
puts car.model

AError: attr_reader conflicts with manual setter method

BError: undefined method 'model='

CError: attr_reader does not create setter method

DNo error, code runs and prints 'SUV'

Step-by-Step Solution

Solution:

Step 1: Check attr_reader and setter method
attr_reader :model creates a getter method. The setter method model= is manually defined.
Step 2: Analyze method calls
car.model = 'SUV' calls the manual setter, updating @model. puts car.model calls the getter from attr_reader, printing 'SUV'.
Final Answer:
No error, code runs and prints 'SUV' -> Option D
Quick Check:
attr_reader + manual setter works [OK]

Quick Trick: attr_reader + manual setter is valid [OK]

Common Mistakes:

Assuming attr_reader creates setter method
Thinking attr_reader conflicts with manual setter
Expecting error on model= assignment
