Tension within a team is usually created due to differences in opinion. Explain to the interviewer how you would handle such a situation, while keeping the best interest of the project in mind.

"I always believe in my team and clearly there was a reason they all preferred option B. I would ask their reasoning behind the preference. Given their explanation if I felt as if the project would be more successful using option B, I would definitely be on board. I don't take those types of things personally. At the end of the day, it's about what will create the best possible results for the given project."
