If k is the sum of the digits of integer m, and m=12n, where n is an integer, which of the following must be true?	Choose the correct choice from the following answers:	A) k is not divisible by 9	B) The sum of the digits of k is divisible by 3	C) m is a multiple of 2k	D) k is a multiple of 9	E) k is a multiple of 6
m= 12n i.e n =1,2,3 ,4 etc or -1,-2.-3 ,-4 then m =12,24,36,48 or -12 ,-24 ,-36 ,-48 then k 3,6 9,12 or -(1+2) , -(4+2) , -(3+6) ,-(4+8) .   ans The sum of the digits of k is divisible by 3
