Hi,

I got the answer correct, but i am confused with choice C.

In A--> Pronoun "it" has no clear referent so i eliminate this option.
In D--> "that" is required after "show" because it is a reporting verb. Again pronoun "it" has no clear referent. So, these were the two reasons i eliminated this answer choice.
In E--> "that" is required after "show" because it is a reporting verb. So eliminated this choice.
In C--> O.G says "saves" does not have subject. (Can anyone please explain this in more detail ?)
In B--> This was the only answer that looks better than others, so i chose this option.

The context talks about parallelism - scale burning, forest thinning, and the training of fire management personnel.

Is the parallelism between noun, noun, and noun ?

Thanks & Regards
Sachin
