(1) m is divisible by 3
if m = 3 , ans is NO
if m = 6, and is yes
INSUFF
(2) m is divisible by 4
if m is 4 , Ans is NO
if m is 24, Ans is yes
INSUFF
1+2
Taking the LCM of 4 and 3 we see that m is a multiple of 12
hence m will always be divisible by 6
SUFF.
Ans- C

Test cases!
Statement 1: m could be 3, in which case the answer is 'no'. Or, m could be 6, in which case the answer is 'yes'. Two different answers = not sufficient. Eliminate A and D.
Statement 2: m could be 4, in which case the answer is 'no'. Or, m could be 12, in which case the answer is 'yes'. Two different answers = not sufficient. Eliminate B.
Statements 1 and 2 together: If you aren't sure about the theory, try some numbers that are divisible by both. One way to do this would be just listing numbers:
divisible by 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ...
divisible by 4: 4, 8, 12, 16, 20, 24, 28, 32, ...
On both lists: 12, 24, ...: all will be divisible by 6, so the answer will be 'yes'. The statements together are sufficient.
Or, with some Number Properties: a number divisible by 3 will have 3 as one of its prime factors. A number divisible by 4 will be even. An even number that's divisible by 3 will definitely be divisible by 6, so the answer will be yes. The answer here is C.
