<h2>C) Differentiated cells have the same DNA, but they do not activate all parts of their DNA</h2>
Explanation:
The formation of every cell takes place by a single cell that is zygote so contain the same DNA. After maturation when the functions of the cells differentiated due to activation of the different parts of the DNA then such process is known as differentiation. Thus cells show different functions on the activation of different genes that are present on the chromosomes.
