being done与done作状语

being done与done作状语Some of the suspects ____ refused to answer and kept their mouths shut.A.questioning B.being questioned.C.questioned.D.to be questioned.我觉得选B,因为句意为被询问的嫌疑犯闭口不谈,如果选C,那不就成了已经被询问过了的嫌疑犯闭口不谈,为什么不用BEING DONE强调一下当时正在发生呢?being done可以强调过去正在进行的事情吗?thank you so much if you can answer this question!
