Final answer:
The correct answer is option 3, which is that only applications, sections, and modules with names containing 'service' would be included in the Navigator filter results.
Step-by-step explanation:
When entering "service" in the Navigator filter, the results would generally include any application, section, module, or other items that contain the word "service" within their names. Therefore, the correct answer is 3) Only applications, sections, and modules with names containing 'service'. This means that if you have an application named Service Desk, for example, all modules and sections under the Service Desk application would appear in the search results because they are part of an application whose name contains "service". Similarly, any module with the name containing "service" or "services" would be included in the results as well.
