Select the true statements related to PEP 8 programming recommendations for exception handling.

The correct answers are C and D. Custom application exceptions should normally inherit from Exception, not directly from BaseException. BaseException is intended for system-exiting exceptions such as SystemExit, KeyboardInterrupt, and GeneratorExit, so deriving ordinary errors from it can interfere with normal control flow. PEP 8 also discourages broad or bare except: clauses because they catch too much and can hide programming errors or prevent expected interruption behavior. Specific exception handling is clearer, safer, and easier to debug. Option A reverses the intended guidance: exception hierarchies should help code distinguish what went wrong programmatically. Option B is false because a bare except: can catch system-level exceptions, which is exactly why it should be avoided.
