If k is the sum of the digits of integer m, and m=16n, where n is an integer, which of the following must be true?
Choose the correct option.
A) k is not divisible by 9  B) The sum of the digits of k is 9  C) m is a multiple of 2k  D) k is a multiple of 9  E) k is a multiple of 6
m= 16n i.e n =1,2,3 ,4 etc or -1,-2.-3 ,-4 then m 16,32,48,64 or -16 ,-32 ,-48 ,-64 then k 7,5 12,10 or -(1+6) , -(3+2) , -(4+8) ,-(6+4)   ans k is not divisible by 9
