Answer:
D)One big superclass can be used instead of many little classes.
Explanation:
Inheritance could be described as getting new class on another existing class with almost same execution,
inheritance allows codes to be re-used. It should be noted that inheritance bring about the code sharing among class.
The advantages of using inheritance includes but not limited to
✓ Code that is shared between classes needs to be written only once.
✓Similar classes can be made to behave consistently.
✓ Enhancements to a base class will automatically be applied to derived classes.
Answer:
Written using C++

#include<iostream>
#include<cmath>
using namespace std;
int main()
{
//1
float side;
cout<<"Enter the side of a square: ";
//2
cin>>side;
//3
float perimeter = 4 * side;
cout<<"The perimeter is "<<perimeter<<endl;
//4
float area = side *side;
cout<<"The area is "<<area<<endl;
//5
float diagonal = sqrt(2 * side * side);
cout<<"The length of the diagonal is "<<diagonal;
return 0;
}

There are six categories of security services: authenticiation, access control, data confidentiality, data integrity, nonrepudiation, and availability service. First, is authentication service, which defines as the assurance that the communicator is legitimate and is the one that it claims to be. It can either be peer entity or data origin authentication. Second, access control which is to prevent any unauthorized uses of resources. After one is being authenticiated, then this service limit/controls who access? what accessing rights to the resources are allowed depending on the identified individuals. Data confifentiality: the protection of data from unauthorized disclosure. Data integrity: the assurance that data received are exactly as sent by an authorized entity (e.t.c, contain no modificafion, insertion, deletion, or replay).
