Q10. You are creating a new class named Polygon. You write the following code: 

class Polygon : IComparable 

{ 

public double Length { get; set; } 

public double Width { get; set; } 

public double GetArea() 

{ 

return Length * Width; 

} 

public int CompareTo(object obj) 

{ 

// to be completed 

} 

} 

You need to complete the definition of the CompareTo method to enable comparison of the Polygon objects. 

Which of the following code segments should you use? 

A. public int CompareTo(object obj) 

{ 

Polygon target = (Polygon)obj; 

double diff = this.GetArea() - target.GetArea(); 

if (diff == 0) 

return 0; 

else if (diff > 0) 

return 1; 

else return -1; 

} 

B. public int CompareTo(object obj) 

{ 

Polygon target = (Polygon)obj; 

double diff = this.GetArea() - target.GetArea(); 

if (diff == 0) 

return 1; 

else if (diff > 0) 

return -1; 

else return 0; 

} 

C. public int CompareTo(object obj) 

{ 

Polygon target = (Polygon)obj; 

if (this == target) 

return 0; 

else if (this > target) 

return 1; 

else return -1; } 

D. public int CompareTo(object obj) 

{ 

Polygon target = (Polygon)obj; 

if (this == target) 

return 1; 

else if (this > target) 

return -1; 

else return 0; 

}
