Answer:
1. Classes and objects
2. Inheritance
3. Polymorphism
4. Data hiding/ encapsulation
5. Interfaces.
Explanation:
Classes and objects depict the major component of the OOP (object oriented programming). It explains the object like a ball in a soccer game development.
The inheritance is like the subclass of the object. Data hiding is a stage in oop where the codes or data are hidden from another users.
In the polymorphism stage, the object is given the ability to change to a sub-object, while in the interface stage a function or method signature is defined without implementing it.

Answer:
C. Address Resolution Protocol (ARP) poisoning.
Explanation:
An antivirus signature file is a program written to describe and remedy a group of identified malware attacks, to prevent future attacks from the described malicious softwares. It is constantly updated to identify more malicious softwares.
A network access protocol (NAC) is used to implement access control on a network, collaborating with other protocols like ARP and unifying antiviruses, intrusion detection and vulnerability assessment.
When the virus signature file is out of date, the NAC allows a new malware, the antivirus can not identify, to access the network through ARP poisoning.
