To determine the correct answer for this question, we need to understand the syntax for accepting any number of double values and returning an array of double values.
Option a) public static double... convert(double... d) declares a method that accepts any number of double values using varargs (denoted by "...") and returns a double array. This is a valid header for a method that meets the requirements.
Option b) public static double... convert(double[] d) declares a method that accepts an array of double values, not any number of double values. Therefore, it does not meet the requirements.
Option c) public static double[] convert(double... d) declares a method that accepts any number of double values using varargs and returns a double array. This is also a valid header for a method that meets the requirements.
Option d) public static double[] convert(double[] d) declares a method that accepts an array of double values, not any number of double values. Therefore, it does not meet the requirements.
So, the correct answer is either a) or c). Both options a) and c) show valid headers for a method that accepts any number of double values and returns an array of double values.
Hope this helps!
