Answer:

<em>The correct option is A) The cell theory is the result of explanations of scientists' observations and not a  description of the cell structure as it relates to the function.</em>

Explanation:

The cell theory can never become a law because Scientific theories are well-tested explanations, while laws are well-tested descriptions of  natural phenomena; one cannot become the other.

A scientific theory is subjected to be changed overtime but a law cannot change. We have observed many changes in the cell theory in the past and we might find changes in this theory in the future also. Hence, the cell theory can never become a law.
