IMO A

Eliminated B and C at the first look.

D looked good but has a modifier problem at the end (this substitution)

check grammar

d is wrong. "while" is wrong

C. if these fertilizers are used increasingly, they can create serious environmental problems such as water pollution, and if used as substitutions for more traditional fertilizers, they

this statement has two if's which is awkward and also wordy. hence C is out.

C looks to be an interesting choice...

Is this for the form :
... if x y and if x y ...

... if used as substitutions for more traditional fertilizers, they ...

"they" might refer to traditional fertilizers

[spoiler]A

C[/spoiler] changes the meaning of the sentence slightly by making it conditional.
