Contrary to the assumption that modern technology allows us to improve

I think B is wrong because observation of a representative case, case of a watch in this question, can affect the changes in mechanical case only and not in natural system. The observations of mechanical system can not be applied to project changes in a natural system.

Contrary to the assumption that modern technology allows us to improve on nature, it is clear that any major technologically induced changes in a natural system are likely to be detrimental to that system. If you were to open the back of your watch, close your eyes, and poke a pencil into the exposed works, the almost certain result would be damage to the watch. Living organisms too, when subjected to technological alteration, will almost certainly be damaged rather than improved.

The argument above is developed by

(A) citing a consensus of opinion about technology among informed observers - WRONG. No consensus is observable from the passage.
(B) projecting the effects of change in a natural system from observation of a representative case - WRONG. 'representative case' is the spoiler here.
(C) drawing an analogy between a natural system and a mechanical device - CORRECT. Yes, true that analogy is drawn - right or wrong, we are not concerned.
(D) analyzing a natural system in terms of its constituent parts - WRONG. No analysis here and also what constituent parts.
(E) examining the results of technological innovations of the past - WRONG. What past?? It's a hypothetical situation mentioned in the passage.

Answer C.

Hi Expert,

Request you to explain the difference between options C and B as they sound similiar to me.
