I feel like I might be leaning towards option C, but I really need to double-check my calculations before committing to an answer.

I think I need to use the third central moment in the calculation, but I'm a bit confused about how to find it from the given statistics.

This question seems similar to the practice problems we did last week, but I can't recall the exact formula for the coefficient of skewness.

I remember we discussed skewness in class, but I'm not entirely sure how to apply the central moments here.
