The Type II error refers to the situation where we fail to reject the null hypothesis when it is actually false. In this case, the null hypothesis is that there is no difference in health benefits between EnerG and Supreme. The Type II error would be to conclude that there is no difference in health benefits between the two brands (i.e., EnerG is no more nutritious than Supreme) when EnerG actually provides more health benefits. Therefore, the correct choice is B.
