Option A is the valid heading for a method which takes an array as input parameter. The heading "void DisplayOutput(double [ ] anArray)" specifies that the method expects an array of doubles as input, and the name of the array parameter is "anArray". The square brackets "[]" indicate that an array is being passed, but the size of the array is not specified. If the size of the array was specified (as in option B or D), it would result in a compilation error. Option C is also incorrect as it does not specify that an array is being passed.
