Answer:

The arrest of the division that occurs when animal cells that are growing in a Petri dish and form a single, unbroken layer on the bottom of the dish is an example of density-dependent inhibition (option C).

Explanation:

The animal cell must divide in order to form a tissue or repair it in case of being damaged, counting on regulation mechanisms that allow an adequate and sufficient growth.

Density-dependent inhibition is a mechanism for controlling cell growth that limits cell reproduction to a certain point. When cells are cultured, they can be seen to grow by covering the bottom of the Petri dish, but their division ceases when they occupy the available space. This implies that the agglomeration of cells prevents them from continuing to divide.

The amount of nutrients needed for cell culture growth limits this growth, since cell division depends on the amount of resources available to support a given cell population, which explains the density-dependent inhibition.
