To answer this question, you need to understand the concept of a symbolic map.
Option A) A link edit map - This option is incorrect because a link edit map is used during the linking process to resolve symbolic references between program modules.
Option B) A map of all the entry points in the CICS region - This option is incorrect because a symbolic map is not related to the entry points in a CICS region.
Option C) A copybook member that is included into the source. It contains code defining the fields on the map - This option is correct. A symbolic map is a copybook member that is included in the source code. It contains code defining the fields on the map, such as the field names, lengths, and types.
Option D) The load module that is loaded into the CICS region when a program sends a map - This option is incorrect because a symbolic map is not the load module that is loaded into the CICS region. It is a copybook member used during the source code compilation.
The correct answer is C) A copybook member that is included into the source. It contains code defining the fields on the map. This option is correct because it accurately describes what a symbolic map is.
