I gave my students this multiple choice question: The classification of some organisms has changed. Which new process is used to reclassify organisms?

Only one answer is correct among these 4 choices:
- Organisms are now given Latin-based scientific names.
- Structures are now examined at the molecular level.
- Organisms are now divided into three kingdoms.
- Structures are now used to classify organisms.

Could you tell me which one is correct?
