Find the error in this Ruby class declaration:

class Person
  def initialize(name)
    @name = name
  end

  def name
    @name
  end

  def name=(value)
    @name = value
  end

end

p = Person.new("Alice")
p.name = 123
puts p.name

AError: cannot assign integer to name

BNo error, code runs and prints 123

CMissing 'end' for class

DCannot use '@name' instance variable

Step-by-Step Solution

Solution:

Step 1: Review class and methods
The class defines an initializer, a getter, and a setter for @name. Ruby allows any type for instance variables.
Step 2: Check code execution
Creating a Person with "Alice", then setting p.name = 123 changes @name to 123. Printing p.name outputs 123.
Final Answer:
No error, code runs and prints 123 -> Option B
