Answer:

<em>The correct option is C) Cells do not use the same sections of DNA in the same proportions, at the same time in development, which leads to differentiation.</em>

However, each cell is specialized to perform a different function because a part of the DNA which is active in one cell might not be active in the other cells.

As a result, variations occur in the structure and function of different cells.
