Correct Answer is: A

The sentence is a simple example of a complex sentence. The phrase "for instance" introduces a specific example of how learning a second language can be beneficial, and the phrase "the ability to communicate in a second language" is the subject of the sentence. Choice B is incorrect because a comma and semicolon are used to join two independent clauses, but the semicolon should be followed by a conjunction. Choice C is incorrect because a semicolon is used to join two independent clauses, but the semicolon should be followed by a conjunction. Choice D is incorrect because no punctuation is needed between two independent clauses that are not joined by a conjunction.
