Wait, isn't the t-distribution used when the population variance is unknown? I'm going with D, the estimated mean divided by the estimated standard deviation has a Chi2-distribution.

I'm pretty confident it's C. The standard deviation is the square root of the variance, so the estimated mean divided by the estimated standard deviation has a t-distribution.

I'm not sure, but B sounds right to me. The estimated mean divided by the estimated variance has a Chi2-distribution, right?

Hmm, I think it's C. The estimated mean divided by the estimated standard deviation should follow a t-distribution for i.i.d. normally distributed observations.
