I need help with this question somebody answer!!

Answer:

The essential factor to increase the number of cells in a growing organism is that each and every cell has a complete copy of DNA.

Explanation:

The development and growth of an organism is based on the multiplication of its tissue cells. Cell multiplication in somatic cells occurs through mitosis, a process that allows obtaining two identical daughter cells from a progenitor cell.

DNA contains all the genetic information belonging to a living organism. In the process of mitosis, the DNA of each cell must be replicated so that each daughter cell has a complete copy of the original DNA. This ensures that each cell resulting from mitosis has the same structure and function as the original cell.

The other options are not correct because:

The size of the cell is important, since each cell has defined characteristics, according to the tissue it must form.
Each and every cell needs to have a complete DNA.
In somatic cells, DNA does not vary from one cell to another.
