B) the independent variable has a small effect
C) you were unable to detect an effect of the independent variable with your experiment

The tail probability of 0.0900 means that the probability of obtaining a result as extreme or more extreme than what was observed is 0.0900. This is greater than the significance level of 0.05, which means we fail to reject the null hypothesis. Thus, we can conclude that we were unable to detect an effect of the independent variable with our experiment.
