Answer:
b. foreign key
Explanation:
In the database world, a foreign key is a field on one table and a primary key for another table. The purpose of a foreign key is to provide linkages between two or more tables. Given two tables A and B, and making A the point of reference, a primary key is a field that is unique in A while a foreign key is unique in B.
On another hand, a composite primary key is a combination of two or more fields/columns on database table that can be used to uniquely identify each row in the table.
In the database lingua, what we have is a unique key not a distinct key, though the two words are similar in meaning.
A duplicate key is used when an information may be repeatedly entered on a table.
So the correct option is a foreign key.

Answer:
See explaination
Explanation:
#include <iostream>
using namespace std;
class Circle{
// private member variable named radius
private:
double radius;
// get function for radius
public:
double getRadius(){
return radius;
}
// set function for radius
void setRadius(double rad){
radius=rad;
}
// returning area = 3.14159 * radius * radius
double getArea(){
return (3.14159 * radius * radius);
}
};
// Sample run
int main()
{
// Declaring object of Circle
Circle myCircle;
myCircle.setRadius(5);
// printing radius of circle
cout<<"Radius of circle is: "<<(myCircle.getRadius())<<endl;
// printing area of circle
cout<<"Area of circle is: "<<(myCircle.getArea())<<endl;
return 0;
}
