C. To send his son back to the cemetery
Answer: I would say “Hey, this way!”
Explanation:
It sounds more polite than the other option & it’s probably what I would choose to say
When I was afraid is the subordinate clause because "that is the time" can stand by itself and can be recognized as a independent clause. I believe that the subordinate clause would fall under the adjective clause family, mainly because "when I was afraid" directly refers to "time", which is a noun.
