Which scan method is slower and more thorough in detection?

The correct answer is detailed search, as this scan method is specifically designed to be more comprehensive and meticulous in its detection processes. A detailed search involves a systematic and exhaustive examination of the area or subject of interest, leaving no stone unturned. This thoroughness ensures that even the most subtle details or hidden elements are identified, which is crucial in situations where accuracy and completeness are paramount, such as in security operations or technical inspections.

In contrast, the other scan methods, though useful for quicker assessments or general observations, do not prioritize the same level of thoroughness. For example, a rapid scan is intended to quickly assess a situation to identify any immediate threats or issues, potentially overlooking finer details in the process. Both horizontal and vertical scans are also more focused on broader coverage rather than the depth of analysis, making them less suited for situations that demand an exhaustive search. Thus, the detailed search is the method that balances thoroughness with the necessary rigor needed for comprehensive detection.
