Final answer:
If you fail the drivers test the first time you may retake it in another month.
Step-by-step explanation:
If you fail the written driver's test the first time, you may retake it after a certain period of time. The amount of time you have to wait to retake the test depends on the state in which you are taking the test. Option C, 'in another month,' is the correct answer in this case, as it is a common waiting period for retaking the test in many states.
Therefore, the answer to this question is C. in another month.
