If the Apache Web Server Discovery Pattern has a step configured to collect the Configuration file data but NOT configured with a step to collect the Version information, what will happen when executing a Service Mapping discovery?
A. An identification error will occur.
B. The Apache Web Server CI will be reclassified as a Web Server CI.
C. The Apache Web Server configuration item will be discovered successfully and either inserted or updated in the CMDB.

Can you give me the correct answer and a detailed explanation?
