    D is true. since 50 has more factors other than 1 and 50 itself. 50 also is 10x5 = 25x2

    A composite number is one having factors other than 1 and the number itself. A prime number is one having only 1 and the number itself has factors. Hence 13 is prime bcoz only 13x1 = 13 and there is no other way of dividing 13 fully. :)
