BAn empty list of log streams
CA list of all log streams in all groups
DA list of log streams with default values
Step-by-Step Solution
Solution:

  1. Step 1: Understand describe-log-streams behavior

    If the specified log group does not exist, AWS CLI returns an error indicating the group is missing.

  2. Step 2: Confirm no empty or default output

    The command does not return empty lists or streams from other groups; it strictly requires the group to exist.

  3. Final Answer:

    An error indicating the log group does not exist -> Option A

  4. Quick Check:

    Describe streams for missing group = error [OK]
Quick Trick: Describe-log-streams errors if group missing [OK]
