Choice B is incorrect because using '首先' would indicate continuing development rather than concluding - students may not recognize that conclusions don't introduce new arguments. To help students: Teach recognition of concluding phrases and the typical elements of a conclusion (summary, final thoughts, acknowledgments). Practice identifying when speakers shift from developing ideas to wrapping up their presentation.
