The answer is "Option b"
Explanation:
In the given code three-class C1, C2, and C3 are declared, in which C2 and C3 extend the class C1. In the next line, C2 and C3 object are created, that is c2 and c3. and in the last line c2 class object holds two-class C2, C1, and one object c3 value, this code will give runtime error because it can't cast object from sibling class, and wrong choices can be defined as follows:
- In option a, It is not correct because it can't cast c3 object into c2 object.
- In option c, It is not correct because it performs multiple casting in nested forms.
- In option d, It is wrong because the statement is not correct.

Explanation:
A proxy server, for example, can hide the true origin of a request, thus, keeping your IP address private, and non-visible to the internet. However, this won't necessarily keep malicious attackers from reaching your network. A proxy simply acts as an intermediary between you, and the server you are trying to reach.
Firewalls or an Intrusion Detection Systems (IDS) are pieces of software specifically designed to keep attackers out of your system, they can analyze the web traffic and detect malware, or they can prevent the delivery of some packages, based on its content if the IDS consider it's malicious.
Your answer is A.
