Answer the following question given this paragraph: 

Binary fission in various single-celled organisms (left). Cell division is a relatively simple process in many single-celled organisms. Eventually the parent cell will pinch apart to form two identical daughter cells. In multiple fission (right), a multinucleated cell can divide to form more than one daughter cell. Multiple fission is more often observed among protists.


Q: Where is multiple fission more often observed?

 Choices:

- among multi-celled organisms

- among animals

- among vertebrates

- among protists

A:
among protists
