Identify the error in this Ruby code snippet:

class Parent
  def greet
    "Hello"
  end
end

class Child < Parent
  def greet
    super()
  end
end

Child.new.greet(1)

BNo error, outputs 'Hello'

CError: wrong number of arguments (given 1, expected 0)

DError: undefined method greet for Child

Step-by-Step Solution

Solution:

Step 1: Check method definitions and arguments
The parent greet method takes no arguments. The child calls super() which calls parent with no arguments.
Step 2: Check method call on Child instance
The call Child.new.greet(1) passes 1 argument, but greet expects none, causing an argument error.
Final Answer:
Error: wrong number of arguments (given 1, expected 0) -> Option C
