Given this code, which choice would be expected to be a true statement if the user requests the index action?
class DocumentsController < ApplicationController
before_action :require_login
def index
@documents = Document.visible.sorted
end
end
a. The user's documents will be loaded.
b. The index action will run normally because :index is not listed as an argument to before_action.
c. The require_login method will automatically log in the user before running the index action.
d. The index action will not be run if the require_login method calls render or redirect_to.
