Research indicates that the health of all multicellular organisms, including humans, depends on not only the ability of the organism to produce new cells but also whether individual cells are able to self-destruct when they become superfluous or disordered.

A. including humans, depends on not only the ability of the organism to produce new cells but also whether individual cells are able
B. including humans, not only depends on the organism's ability to produce new cells but also the ability of individual cells
C. including humans, depends not only on the organism's ability to produce new cells but also on the ability of individual cells
D. which includes humans, depends on not only the organism's ability to produce new cells but also depending on the ability of individual cells
E. which includes humans, not only depends on whether the organism is able to produce new cells but also on the ability of individual cells

This one is very fairly straightforward. It involves the idiom:

NOT ONLY | x
BUT ALSO | y

Where x and y are reasonably parallel.

Answer choice (A) offers us:

not only | the ability of...
but also | whether individual cells...

The above is not parallel.

By comparison, answer choice (C) offers us:

not only | on the organism's ability...
but also | on the ability of individual cells...

That's why (C) is the best answer.

Other defects include (D) and (E) both of which offer us:

all multicellular organisms, which includes humans...

However includes does not go with the subject multicellular organisms.
