It is given that the sample statistic B is an unbiased estimator of the population parameter $\alpha$.
Here, A and B are unbiased estimators of $\alpha$. The standard deviations of A and B should be compared for deciding the best estimator of $\alpha$. The best estimator of $\alpha$ is the statistic that has the smaller standard deviation.
