Consider the following code.
// Insertion Point 1
using namespace std;
const float PI = 3.14;
int main()
{
//Insertion Point 2
float r = 2.0;
float area;
area = PI * r * r;

cout << "Area = " << area < return 0;
} //
Insertion Point 3

In this code, where does the include statement belong?
a. Insertion Point 1
b. Insertion Point 2
