Bean Scopes Suppose you are working on an application that involves encrypting passwords before storing them in the database. The encryption part is carried out by a PasswordEncryptor class. This class provides you with a method that takes a plaintext password and returns an encrypted one. You need to create a bean of this class. What should be the scope of this bean? Choose the correct option from those given below. (Hint: PasswordEncryptor only contains methods and no fields to maintain state. Hence, we need to create a stateless bean of PasswordEncryptor. Recall which bean scope is used for creating stateless beans.)   1) Prototype   2) Singleton   3) Request   4) Session Provide right solution
