Java ### Understanding the `getArea` MethodThe following is an explanation of the `getArea` method from a textbook:```javapublic int getArea(){ if (width <= 0) { return 0; } // line #1 if (width == 1) { return 1; } // line #2 Triangle smallerTriangle = new Triangle(width - 1); // line #3 int smallerArea = smallerTriangle.getArea(); // line #4 return smallerArea + width; // line #5}```#### Method Explanation- **Line #1:** Checks if the `width` is less than or equal to 0. If true, it returns 0.- **Line #2:** Checks if the `width` is exactly 1. If true, it returns 1.- **Line #3:** Creates a new `Triangle` object with a `width` decreased by 1.- **Line #4:** Recursively calls `getArea` on the new `Triangle` object and stores the result.- **Line #5:** Returns the sum of `smallerArea` and `width`.### Modification and ImpactThe instruction assumes a change in line #3:- **Changed Line #3:** ```java Triangle smallerTriangle = new Triangle(width); ```### ImplicationThis change causes infinite recursion. Specifically:- This would lead to infinite recursion for ___. - ☐ triangles with width equal to 1 - ☐ triangles with width equal to 0 - ☐ triangles of any width - ☐ triangles with width greater than or equal to 2#### ExplanationThe modified line creates a new `Triangle` of the same `width`, not reducing it by 1. When `getArea` is called recursively, it always uses the original `width`, causing endless recursion when the `width` is 2 or more.

As we can see, 3rd line is- Triangle smallerTriangle=new Triangke(width) which will create object for Triangle as smallerTriangle and pass width parameter to constructor of Triangle. But as we can see, in our code, no parameterized constructor is mentioned. So program will infinitely find for the constructor and this will cause infinite recursionHence, Correct Answer is - Triangle of any width

Consider the getArea method from the textbook shown belov public int getArea() if (width <= 0) { return 0; } // line #1 if (width Triangle smallerTriangle = new Triangle (width - 1); // line #3 int smallerArea = return smallerArea + width; // line #5 1) { return 1; } // line #2 %=D%3D %3D smallerTriangle.getArea (); // line #4 Assume that line #3 is changed to this: Triangle smallerTriangle - new Triangle (width); %3D This would cause infinite recursion for 51- O triangles with width equal to 1 O triangles with width equal to 0 triangles of any width O triangles with width greater than or equal to 2
