Explanation:

1. For the first part about gene - editing transition: Option A provides background information about gene - editing, which can be a good lead - in. Option B is a question that may not be the best transition. Option C is a negative opinion and not a good transition. Option D is a strong statement about the consequence of gene - editing and not a good transition.
