What is likely to happen to communication systems during a national crisis?

During a national crisis, communication systems often experience an overwhelming surge in usage, as many individuals and agencies attempt to communicate simultaneously. This influx of traffic can lead to system overloads, which may significantly hinder the ability of personnel to effectively respond to emergencies. Networks may become congested or fail altogether, impacting both the dissemination of critical information and coordination among emergency responders. Consequently, the correct choice highlights the challenges that communication systems face under the strain of increased demand during such critical situations.

In contrast, suggestions of increased efficiency or quick restoration are not typically accurate, as systems can be strained beyond typical operational capacity. Handling emergencies remotely does not fully address the on-the-ground requirements and complexities often faced during a national crisis, making it less likely as a correct response.
