From the information provided I would say no, but there could be some traps here
1. If Hall does not acknowledge the work of Bishop there could be plagerism therefore misrepresentation.
2. If Hall does not satisfy himself that Bishop’s work is solid there could be an issue with diligence and reasonable basis
3. If Bishop was overly friendly with company officials during the visit and pervayed this in the report there could be issues with objectivity.
But the question mentioned none of these issues so I am going with D.
