Manhattan CAT-2 question

[aashray.thatai]

Heres a CR assumption form CAT-2 MGMAT
"Disposable diapers, while a convenience, are an environmental disaster. If people would use cloth diapers instead of those made of disposable paper, much less paper would be produced saving millions of trees each year. Therefore, people should go back to buying, washing and reusing cloth diapers and Earth’s precious natural resources would not be consumed so rapidly. "

This argument depends of which of the following assumptions?

a) Cloth diapers are never disposed of.
b)The current trend in infant care is doing things "the old-fashioned way."
c)dThe process of washing cloth diapers consumes less natural resources than that of using disposable diapers.
d)Modern people like their conveniences more than anything else.
e)The annual cost to the consumer of using cloth diapers is only 20% the annual cost of using disposable diapers

I was confused between c and d. The problem i ran into with C was that using the negation test i was getting "more natural resources are consumed".which changes the conclusion ? could you please explain how do correctly approach this question !!
Thanks

This is not a "problem"; this is exactly what's supposed to happen in the "negation test".
When you make an assumption false, the entire argument should be destroyed.
