Given this code, and assuming @user is an instance of User that has an assigned location, which choice would be used to return the user's city?

    class Location < ActiveRecord::Base
        # has database columns for :city, :state
        has_many :users
    end
    class User < ActiveRecord::Base
        belovngs_to :location
        delegate :city, :state, to: :location, allow_nil: true, prefix: true
    end
