Correct Answer: B
Choice B is the best answer. This question tests comma usage after introductory participial phrases.
- Context clues: A participial phrase introduces the main clause.
- Meaning: Use a comma after an introductory participial phrase.
- Verify: "Having analyzed the data thoroughly, the researchers published..." correctly separates the introduction.

Choice A is incorrect because it lacks the required comma. Choice C is incorrect because the comma splits the phrase incorrectly. Choice D is incorrect because the comma after "Having" is grammatically wrong.
