Living things has emerged into three domains called Archaea, bacteria, and eukaryotes. Evident that support the idea that multi cellular that is eukaryotic cell evolved from the prokaryotic cell are the descendents of the separate prokaryotic cells that together form a union which are inter dependent.
For example: The mitochondria which is referred to the energy source of the cell is considered as the great-great-great-granddaughter of a bacterium cell which is free living. This free living bacterium bacterial cell was consumed by an other cell and this remained as the stable guest in the cell. This mitochondria provided chemical energy to the cell and also protected the nutrient rich environment. which surrounds it. This process of one organism residing in the other organism completely is called endosymbiosis.
I will go with choice (C) density dependent pattern

Amphicoelias altus (from the gr. "Hollow character on both high sides") is the only known species of the extinct genus. Titoniense, in what is now North America. Amphicoelias is present in stratigraphic zone 6 of the Morrison Formation
It was also similar in size to Diplodocus, about 25 meters long. Although most scientists have used this data to distinguish Amphicoelias and Diplodocus as separate genera, at least one has suggested that Amphicoelias is probably the largest synonym for Diplodocus.3 Amphicoelias altus, was named by paleontologist Edward Drinker Cope in December of 1877, although it was not published until 1878, for an incomplete skeleton consisting of two vertebrae, a pubis, the hip, and a femur, bone of the upper leg.4 Cope also named a second species, A. fragillimus
