Explanation
Velocity is a measure of how much work a team can complete in an iteration. It is based on the team's historical performance and estimation accuracy. During iteration execution, a team's velocity tends to be most affected by factors that change the team's capacity, collaboration, and context. Changing team size, team makeup, and technical context are examples of such factors. For instance, adding or removing team members, changing team roles or responsibilities, or switching to a different technology or domain can all impact the team's velocity. Therefore, the correct answer is B. Changing team size, team makeup, and technical context.
