To find the LCM of 6 and 11, we need to find the least number that is divisible by both 6 and 11. 
Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, ...
Multiples of 11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110, ...
The first common multiple is 66, but it is not the least common multiple since 66 is not divisible by 6. 
The next common multiple is 132, but it is still not the least common multiple since 132 is not divisible by 11. 
The least common multiple of 6 and 11 is 30, since it is the smallest number that is divisible by both 6 and 11. So, the answer is C) 30.
