Correct Answer: A
Choice A is the best answer. It combines the sentences by making the list of dances part of the subject phrase, flowing naturally into the verb "are still performed."
Choice B is incorrect because the colon is used incorrectly after "such as." Choice C is incorrect because it creates a sentence fragment. Choice D is incorrect because the colon is used after "world" to introduce a list that has already been referred to, which is repetitive and structurally inverted.
