Wasn't there a joke about a statistician who drowned in a river with an average depth of 3 feet? Something about degrees of freedom, I think. Anyway, I'm going with option D.

Hmm, I think it depends on the degrees of freedom for the t distribution. More degrees of freedom means the t distribution approaches the normal distribution.
