OA is [spoiler](E)[/spoiler]. For me [spoiler](C)[/spoiler] seems to be parallel not [spoiler](E)[/spoiler].

E is parallel. Make sure you know what needs to be parallel.

others suggest reducing and still others are calling

IMO C

can we know the source for this question??

I've stuck up between C and E and chose C, as others

I'm not sure, but key words for parallel maybe:

While some propose to combat widespread illegal copying of computer programs by attempting to change people’s attitudes toward pirating, others.......

...(E)suggest [to combat.....by]reducing software prices to decrease the incentive for pirating, and still others are calling

what attract me in C is that "others call"- parallel with propose and suggest, instead of "others are calling" in E.

May we have some professional's comment on this ?

The reason why C is not correct:
"the reduction of software prices for decreasing" is not correct. It should be "to decrease".

E is correct because it maintains parallelism reducing software prices to decrease the incentive for pirating, and still others are calling for the prosecution
