B.) a constant value that is approximately equal to the population mean.

C.) a random variable that is approximately equal to the population mean when sampling is done without replacement.

D.)a random variable that is approximately equal to the population mean if n > 30 and when sampling is done without replacement.

E.)a random variable that when averaged across many samples is approximately equal to the population mean.
