What is the output of this program? class output { class output { public static void main(String args[]) { char c[]={'A', '1', 'b' ,' ' ,'a' , '0'}; for (int i = 0; i < 5; ++i) { i++; if(Character.isDigit(c[i])) System.out.println(c[i]+" is a digit"); if(Character.isWhitespace(c[i])) System.out.println(c[i]+" is a Whitespace character"); if(Character.isUpperCase(c[i])) System.out.println(c[i]+" is an Upper case Letter"); if(Character.isLowerCase(c[i])) System.out.println(c[i]+" is a lower case Letter"); i++; } } }

• A. a is a lower case Letter is White space character
• B. b is a lower case Letter is White space character
• C. 1 is a digit a is a lower case Letter
• D. a is a lower case Letter 0 is a digit
