Answer / Charanjeet Singh
Auxiliary constructors in Scala are used to provide multiple ways for creating instances of a case class. They are defined using the `apply` method and must follow these rules: they should be defined as private, can take any number of arguments (but not variable arguments), and should return an instance of the case class.
