Which of the following is a good reason for us to select a one-tailed test over a two-tailed test?

We think that our effect size will be large, so we want to maximize the possibility of a significant result.

We do not know which direction our effect will go, so focusing on one lets us calculate a simpler statistic.

Results can truly only be in one direction (e.g. measuring growth); it is impossible for them to go the other way based on our research question.

We think that our effect size will be small, so we want to maximize the possibility of a significant result.
