The answer is B.
in order to find the mean, we need the number of values (n) and the actual values.
A - no data on the actual values - insufficient!
B - both the actual values and the number of values (just count them) - sufficient!

When we arrange data in increasing order, middle value is the mean.
Statement 1; doesn't tell us what middle value might be. Thus insufficient.
Statement 2: give us all the data. Here if we arrange increasing order, 0,1,3,4,4,5,5,6
We can clearly see, 4 is middle value and thus mean.
Thus it is sufficient.
Answer is B
