Thus rejecting options (A) , (B) & (D)

Between (C) & (E) , will reject (E) for the highlighted error in (E), hence IMHO (C)

harshpathak96 · Answer

IMO B is best option

C comes close but because of the comma I ruled it out.

A & E are out because of "contaminating", verb tense is wrong here.

D is out because it changes the meaning.

Is my approach correct?

OFFICIAL EXPLANATION

It is important  for the welfare of our ecology to prevent the contaminating of water resources .

(A) for the welfare of our ecology to prevent the contaminating of water resources

Incorrect.

This answer choice is grammatically incorrect. Verb+ing ( contaminating ) can be used as a noun replacement only when there's no actual noun. Since there is a real noun -  contamination  - it should be used.

(B) for the welfare of our ecology to prevent contamination of water sources

Incorrect.

Although this answer choice corrects the original mistake by replacing  contaminating  with  contamination , it changes the meaning of the original sentence, by replacing  resources  with  sources .

(C) to prevent the contamination of water resources, for the welfare of our ecology

Verb+ing ( contaminating ) can be used as a noun replacement only when there's no actual noun. Since there is a real noun -  contamination  - it should be used.

(D) for our ecology and welfare to prevent the contamination of water resource

Incorrect.

Although this answer choice corrects the original mistake by replacing  contaminating  with  contamination , it changes the meaning of the original sentence by replacing the phrase  the welfare of our ecology  with  our ecology and welfare .

(E) to prevent the contaminating of water resources for our ecology's welfare

Incorrect.

This answer choice repeats the original mistake: Verb+ing ( contaminating ) can be used as a noun replacement only when there's no actual noun. Since there is a real noun -  contamination  - it should be used.
