### AI Response: (may contain errors)  

The correct answer to the question about when the station and its records must be available for FCC inspection is:

**B: At any time upon request by an FCC representative.**

### Explanation of the Correct Answer:
- The FCC has the authority to inspect amateur radio stations and their records at any time. This means that if an FCC representative requests access, the station operator must comply immediately. This requirement ensures that the FCC can monitor compliance with regulations and maintain the integrity of the amateur radio service.

### Explanation of the Incorrect Answers:
- **A: At any time ten days after notification by the FCC of such an inspection**  
  This is incorrect because the FCC does not require a waiting period after notification. The inspection can occur immediately upon request.

- **C: At any time after written notification by the FCC of such inspection**  
  This is also incorrect for the same reason as A. The FCC does not need to provide written notification before an inspection; they can request access at any time.

- **D: Only when presented with a valid warrant by an FCC official or government agent**  
  This is incorrect because the FCC does not need a warrant to inspect amateur radio stations. They have the authority to inspect without a warrant as part of their regulatory duties.

### Summary:
- The key takeaway is that amateur radio operators must be prepared for inspections by the FCC at any time upon request. This emphasizes the importance of maintaining accurate records and compliance with regulations.

No specific formulas are needed for this question, but remember the rule of thumb: always be ready for an FCC inspection whenever requested.
