The correct answer is B, 'addressing conflict openly'. Honesty is an important part of trust, and it's vital that members of a team trust each other so that they are able to act in accordance. Every other answer is incorrect because they are superficial and have no actual influence on how well the team works together, and may actually be detrimental. For instance, with answer choice A, 'finding people that you like', you may be too distracted socializing with your team members to work effectively.
Hope this helps!
