AI Explanation

To answer this question, you need to understand the IDMS (Integrated Database Management System) error codes.

The 1205 error code in IDMS represents an error while storing duplicates.

Let's go through each option to understand why it is correct or incorrect:

Option A) Error while disconnecting a record from its set - This option is incorrect. The error code 1205 does not represent an error related to disconnecting a record from its set.

Option B) Error while storing duplicates - This option is correct. The error code 1205 in IDMS indicates an error while storing duplicates. This means that there was an attempt to store a duplicate record in the database, which is not allowed.

Option C) Error while connecting a record to a set - This option is incorrect. The error code 1205 does not represent an error related to connecting a record to a set.

Option D) Error while erasing a record - This option is incorrect. The error code 1205 does not represent an error related to erasing a record.

The correct answer is B) Error while storing duplicates. This option is correct because the error code 1205 in IDMS indicates an error while storing duplicates.
