Hoho, I don't know what's the right answer either, but I put ...
It is desirable for a sample statistic to be unbiased because an unbiased estimator "best" estimates the parameter. A biased estimator estimates a value that is to some degree away from the parameter. So if I want to draw any conclusions or make any decisions based on the population, my conclusion / decision would be more accurate if I use an unbiased estimator.
... I don't like this question at all.
