Consider the following two statements:
I. Cellular organization of the body is the defining feature of life forms.
II. Metabolic reactions cannot be demonstrated outside the body in cell-free systems.
(1) Both I and II are true and II explains I
(2) Both I and II are true but II does not explain I
(3) I is true but II is false
(4) Both I and II are false
(3) Metabolic reactions can be demonstrated outside the body in cell-free systems but they are neither living nor non-living.
