A Texas passenger applicant fails a knowledge test on the initial application date. Which combined retest rule is accurate?

1. Texas keeps the application active for 90 days or three failed attempts, and FMCSA requires a different version for a failed-test retake
2. The applicant must wait one year and retake the identical version
3. The applicant can keep retaking the same version until passing
4. The failed knowledge test can be replaced by a passenger skills test
