The answer would be C

Because 24/8=3 , 72/9=8 , 72/36=2 , 641/81=8 , so all are integers except k/32 , as k divided by 32 wonâ€™t give an integer.

Prime factorisation of 24 is 2^3,3 and that of 16 is 2^4

As k is a multiple of 24 and not of 16, it can never have 4 2s while 32 is 2^5, so k/32 can never be an integer
