Q: Answer-What is the most basic criteria used to decide whether something is alive?

Mostly, any kind of visible movement such as breathing, walking or growing is referred to decide if something is alive or not. But, a living organism may have movements not visible to the naked eye. Thus, it is the presence of life processes that is the basic criteria to decide whether something is alive or not. Hence, option D is correct.
