Haha, this is like a game of 'Guess the Skewness'! I'll go with D. 0.768, just for the fun of it.

Is this a trick question? I'm going to go with C. 0.415. Seems like the safest bet.

Ah, the age-old question of coefficient of skewness! I'll go with A. -0.415. Gotta keep the variance in mind, after all.

D. 0.768 seems more plausible to me. The numbers given are quite large, so the skewness should be higher.
