All of the above :P
The development of chloroplasts led to the oxygenation of Earth's atmosphere, which allowed the evolution of more complex oxygen-breathing organisms.
Complex organisms need cells that perform many different functions. Complex organisms are capable of a lot of different things, and that variety needs to be supported on the cellular level. Without them, complex organisms cannot perform different functions.
Complex organisms evolved from simple organisms, so simple organisms evolved first.
Arthropods are complex organisms. They are made up of cells, tissues, organs, and organ systems.

x2 + 1 can't be factored in the real numbers. If complex numbers are acceptable, it can be factored as (x + i)(x - i).
advantages of human beings are complex organisms

System
The complexity of body design will increase over evolutionary time. This is the process by which new modifications occur in the organisms. So, in this way we can say that advanced organisms will be complex as compared to complex organisms...

human considered complex organism because there are more than 200 organisms in our body
