Has a prospective student-athlete who has started their senior year and meets all requirements qualified for an official visit?

The choice indicating that a prospective student-athlete who has started their senior year and meets all requirements qualifies for an official visit is correct because the NCAA rules state that athletes at this stage in their education can begin to take official visits provided they are registered with the NCAA Eligibility Center. This registration ensures that the student-athlete has filled out the necessary forms and is in compliance with NCAA academic and amateurism standards.

Furthermore, the ability to visit colleges officially is an important step in the recruiting process, enabling prospective student-athletes to explore their options and engage with coaches. The scenarios described in the other choices do not align with NCAA regulations regarding eligibility for official visits. For instance, requiring the athlete to be a sophomore or needing to submit an application are not stipulations defined by the NCAA for official visits, and while having a national test score can be relevant for eligibility, it's not a prerequisite for scheduling an official visit.
