Answer:
d. There is a striking difference in the organizational cultures of the two firms.
Step-by-step explanation:
Numeral d would likely be the argument that would weaken the company's decision to merge with QueenAir.
The reason is that, if the two companies have strikingly different organizational cultures (for example, the American company could have a more traditional, vertical hierarchy, while the British company could be more horizontal and less hierarchical), coordinating them both once the merge is completed could be so difficult as to make the whole process not worth it.
