What are the cellular organization from smallest to greatest

Level 1: a fundamental particle. For example, an electron. They usually weigh less than a yoctogram (the four-hundredth part of a gram). It has no constituent parts that can roam free through space.
Level 2: The electron can associate with other particles to form another individuality, an atom. The atom of hydrogen, for example, does not exceed 1,000 yoctogramos.
Level 3: The atom combines with other atoms and creates another entity, the molecule. There are very light molecules, like the water molecule, and others that are much heavier, like the DNA molecule, which can weigh a picogram (a billionth part of a gram).
Level 4: Molecules can be combined to form a cell. A cell can weigh up to one microgram.
Level 5: Cells can combine with each other to build a larger entity, the organism. There are organisms with a passage between the microgram (a worm) and tens of tons (a cetacean).
Level 6: The organism can meet with other organisms of its same level to give rise to another individuality, the family society of a single mother. For example, a colony of ants.
Level 7: Some families can be grouped into a multifamily partnership. Like a herd of bison.
Level 8: probably the rarest organization of matter, because they are a society of multifamily societies with sovereignty over itself. For example, the Greek polis. Or a state. Its mass can be up to one million tons.
There is no level 9. Although for more than 10 billion years until 3.8 billion, only the first three levels existed. The inert matter.
And it is not until well advanced level seven and the dawn of the eight when, less than a hundred thousand years ago, a tiny part of the intelligent matter accedes to knowledge. It is civilized matter, a matter capable of turning to its history to ask for inert matter, living matter, intelligent matter, itself and its meaning in the future of the universe.

Ithink the answer is a.
