The correct answer is A. 4.
The Length property of a string array returns the number of elements in the array. In this case, the array contains four elements, so the value of len will be 4.
Option B is incorrect because the array is not empty.
Option C is incorrect because the array contains four elements, not three.
Option D is incorrect because the array is not a string, it is a string array.
