The statement about the complexity of life reflects the principle that cells are the basic unit of life. This underscores that all living entities are made of cells, which form the basis for more complex biological structures. While other options in cellular theory are important, they do not directly address the fundamental nature of cells in constructing life's complexity. ;
The best answer to the question is option C, which states that cells are the basic unit of life. This reflects how cells serve as the building blocks for more complex biological structures. Therefore, the complexity of life arises from the organization and functions of these cells.
