Which of the following is an accurate definition of fields within Splunk?

Fields are searchable key/value pairs in event data. They allow you to specify criteria for your searches and filter out unwanted events. Fields can be extracted automatically by Splunk software during indexing or searching, or manually by users using various methods. Fields are not inherent entities that exist in event data, but rather interpretations of data by Splunk software or users. Fields are not values pulled exclusively from lookup tables, although lookup tables can be used to add fields to events based on existing fields. Fields are not non-searchable name/value pairs used while indexing data, but rather searchable attributes that can be used to refine searches5.
