Best Answer Explained in Below-:

The correct answer to the sentence is C: "reached, relayed." This choice fits both contextually and grammatically.

In the context of emergency services responding to an incident, the verb "reached" suggests that the emergency responders arrived at the site of the accident promptly after receiving the information. This aligns with the urgency typically associated with emergencies, where responders must quickly make their way to the location of the incident.

The second part of the sentence uses "relayed," which means that the news of the train collision was passed on or communicated to the emergency services by someone—likely a witness, a bystander, or another official. This term conveys the idea that information was transmitted, allowing the emergency services to act on it, which is a standard procedure in emergency response situations.

In contrast, the other options either use verbs that do not fit the context (like "suspended" or "marked") or do not accurately convey the process of communication and arrival that is critical in an emergency scenario. Therefore, "reached" and "relayed" correctly portray the sequence of events typical in a crisis situation.
