To eliminate the 'NOT CATLG 2' error for a particular dataset, you can follow any of the following approaches:

A. Add a job step to purge the dataset: This option is correct because adding a job step to purge the dataset will remove any existing catalog entries for the dataset. This can be done by using appropriate system commands or utilities.

B. Run a job to purge the dataset and run it before the job that creates it: This option is correct because running a job to purge the dataset before the job that creates it ensures that any existing catalog entries are removed before the dataset is created again. This ensures that the 'NOT CATLG 2' error does not occur.

C. Purge the dataset before running the job that creates it: This option is correct because manually purging the dataset before running the job that creates it will remove any existing catalog entries. This ensures that the 'NOT CATLG 2' error does not occur.

Therefore, the correct answer is D) All of the above. All of these options can be used to eliminate the 'NOT CATLG 2' error for a particular dataset.
