+ AnswerA

+ ExplanationThe natsort() function uses a “natural ordering” algorithm to sort the contents of an array, rather than a simple binary comparison between the contents of each element. In fact, in this example the array is not even touched, since its elements are already in what could be considered a “natural” order. Therefore, Answer A is correct.
