Question

The method below generates all substrings of a String passed as argument. Assuming that the string contains no duplicate characters, select the statement to complete the method so that it prints all substrings correctly. public static void printSubstrings(String word)
{
If (word.length() > 0)
{
For (int j = 1; j <= word.length(); j++) // print substrings that begin
{ // with the first character
System.out.println(word.substring(0, j));
}
___________________________________ // print substrings without
} // the first character
}
A) printSubstrings(word.substring(0));
B) printSubstrings(word.substring(1));
C) printSubstrings(word.substring(word.length()));
D) printSubstrings(word.substring(word.length() - 1));
