Answer: The correct answer is C. as the sentence contains no error.
Explanation: The sentence provided does not contain errors. There is no adverb clause; therefore, incorrect adverb clause placement is inconceivable. Moreover, there is no dangling or misplaced modifier as the adjective clause "who was running around the block" is correctly modifying the noun "jogger". Furthermore, there is not a lack of parallel structure. Taking everything into account, it can be said that the sentence provided contains no error.
