Answer:

The correct answer following question will be Option D.

Explanation:

An authority that verifies the user requests for digital certificates and tells to the CA (Certificate authority) to issue the certificates, known as Registration Authority (RA). The digital certificate contains a key named "public key" which is used to encrypt and decrypt digital signatures.

Hence, registration authority, it's an entity that is responsible for the authentication of certificate and registration and the other given options are not relatable to this authority.

So, option D is the correct answer.

If I have an Animal superclass with a Mammal subclass, both concrete and both having a method called eat() with identical signat
Katarina [22]

Answer:

(c) the dynamic type of reference will determine which of the methods to call.

Explanation:

Polymorphism in Object Oriented Programming typically means the same method name can cause different actions depending on which object it is invoked on. Polymorphism allows for dynamic binding in that method invocation is not bound to the method definition until the program executes.

So in the case of Animal superclass and Mammal subclass, both having a method called eat() with identical signatures and return types, depending on which reference, the correct method eat() will be called dynamically upon execution.

For example, if we have the following;

================================

<em>Mammal mammal = new Animal();</em>

<em>mammal.eat()</em>

================================

The eat() method that will be called is the one in the Mammal subclass.

However, if we have;

================================

<em>Animal animal = new Animal();</em>

<em>animal.eat()</em>

================================

The eat() method of the Animal superclass will be called.
