Answer

Brief Explanations:

In hypothesis - testing, a Type I error occurs when the null hypothesis ($H_0$) is true, but we reject it. This is a fundamental concept in statistics. The other options do not define a Type I error. Option 2 describes a Type II error. Options 3 and 4 are about the nature of null hypotheses in one - tailed and two - tailed tests, not about Type I errors.

Answer:

The null hypothesis is rejected when it is true.
