Which statement about Properties and Validation is the strongest interview answer?

  1. Properties and Validation is mostly a naming style choice and has little effect on runtime behavior or design tradeoffs.
  2. Properties and Validation exists mainly to reduce the number of files in a Python project.
  3. A property lets attribute access carry controlled logic while still presenting a clean attribute-style interface to callers.
  4. Properties and Validation matters only for frontend scripting and not for backend or automation code.
