Answer:
Have each member rate all the ideas and use the one most people like best.
Step-by-step explanation:
Given the situation provided by the exercise, the option that covers the most bases is to have each member rate the ideas that the team has at that moment and pick the one that has the most votes. This way, the frustration can be avoided and Kaleel should not be offended if his idea isn't picked given that each member has the same right to vote for what they believe is the best idea to solve the problem given.
