B. Negatively skewed
C. "Bellshaped"
D. Bimodal

The value of 4 is much further from the mean than 245, especially in terms of standard deviations (1+ vs. almost 5 respectively). It would be negatively skewed (many scores at the high end, relatively few at the low end).

With the same mean and st.deviation, but a min of 55 and a max of 330, what would that be? I just need another example explained...thanks.

Figure how many standard deviations (SDs) above and below the mean each extreme is. If they are approximately equal, it is "bellshaped." If one is significantly further away in terms of SDs, it is skewed in that direction. (You have to decide what is significant.)
There is insufficient data to suggest bimodal.
I hope this helps a little more.
