My Doubts in ruby Inheritance let the Cat help us out.

Ruby Inheritance Doubt

    class Cat
      def self.speak # this is a class method 
        puts "Meow"
      end
    end

    class Lion < Cat
        def roar
          puts "Roar Roar !!!!" #now this is just an ordinary method.
        end
    end

    newcat = Lion.new

    puts newcat.methods.include?("speak") #this produces false
    puts newcat.methods.include?("roar")  #produces true

This means speak method is not present in newcat which is an instance of Lion and inherits from Cat. and speak is a class method in Cat.

"puts Cat.methods" produces a list of what ? 

1) Class methods
2) Instance Methods
3) Protected Methods
4) Public Methods
