I believe the answer is correct.
The declaration
String[][] s = new String[10][];
declares an array named s that refers to an array of 10 elements,
each of which is a reference (null) to an array of String, whose
dimension is unknown (can be initialized to any number you
want).

Yes, the answer is correct. It may also be written as
String[] s[] = new String[10][];

You have a String array of 10 String arrays as Nain Hwu explained.
