Suppose you need to write a method that calculates the volume of a 3D rectangular solid. Which of the following is the best choice for the declaration of this method?
A) public static void volume(int a)
B) public static double volume(double w, double h, double l)
C) public static void volume(double w, double h, double l)
D) public static double volume(double w)

Option B is the best choice for declaring the method because it takes in the width, height, and length parameters as doubles and returns the volume as a double. This allows for a more accurate calculation of the volume of the rectangular solid, and the return type of double ensures that the result is precise. Option A and C have void return types, which means they don't return anything, and option D only takes in the width as a parameter, which is not enough to calculate the volume of a rectangular solid.
