In the biological hierarchy of organization, cells make up tissues, tissues make up organs, organs make up organ - systems, and organ - systems make up organisms. A cell is a basic unit of life, an organ is a group of tissues working together, and an organism is a complete living entity. So an organ is more complex than a cell but less complex than an organism.

Answer:

C. An organ is more complex than a cell but less complex than an organism.
