The end of an action is the intended outcome of the action and not a mere by-product of the action, and the end’s value is thus the only reason for the action. So while it is true that not every end’s value will justify any means, and even, perhaps, that there is no end whose value will justify every means, it is clear that nothing will justify a means except an end’s value.
Which one of the following most accurately expresses the main conclusion of the argument?

(A) The value of some ends may justify any means.
(B) One can always justify a given action by appeal to the value of its intended outcome.
(C) One can justify an action only by appeal to the value of its intended outcome. (OA)
(D) Only the value of the by-products of an action can justify that action.
(E) Nothing can justify the intended outcome of an action except the value of that action’s actual outcomes.
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
I wonder how the answer forms because I cannot get the factor "justify an action" and connect it with "intended outcome".

here is my reasoning:
The end of an action is the intended outcome of the action and not a mere by-product of the action,
end --> intended outcome
end -->~by-product

and the end’s value is thus the only reason for the action.
end's value --> reason

So while it is true that not every end’s value will justify any means,
end's value some justify any means

and even, perhaps, that there is no end whose value will justify every means,
end -->~justify every means

it is clear that nothing will justify a means except an end’s value.
justify a means --> end's value

main conclusion：
nothing will justify a means except an end’s value.
逻辑结构：
justify a means-----》 value of end
--------------------------------------------------------------------------
因为“The end of an action is the intended outcome of the action and not a mere by-product of the action”
所以 end = intended outcome
-----------------------------------------------------
means = action
-----------------------------------------------------
c 选项，是main conclusion的同义改写。
justify action----》 value of intended outcome = justify a means-----》 value of end
