Many people suffer an allergic reaction to certain sulfites, including those that
are commonly added to wine as preservatives. However, since there are several
wine makers who add sulfites to none of the wines they produce, people who
would like to drink wine but are allergic to sulfites can drink wines produced by
these wine makers without risking an allergic reaction to sulfites.
Which of the following is an assumption on which the argument depends?
A. These wine makers have been able to duplicate the preservative effect
produced by adding sulfites by means that do not involve adding any
potentially allergenic substances to their wine.
B. Not all forms of sulfite are equally likely to produce the allergic reactions.
C. Wine is the only beverage to which sulfites are commonly added.
D. Apart from sulfites, there are no substances commonly present in wine that
give rise to an allergic reaction.
E. Sulfites are not naturally present in the wines produced by these wine
makers in amounts large enough to produce an allergic reaction in someone
who drinks these wines.

I chose D can anyone explain if D is correct or wrong with reasons please

Thanks!

I mean if we negate D that we have this

Apart from sulfites, there are substances commonly present in wine that
give rise to an allergic reaction--->so this will make the argument fall apart.....so I think both D and E make the arg fall apart...

Please share your thoughts

The conclusion of the argument is
people who would like to drink wine but are allergic to sulfites can drink wines produced by
these wine makers without risking an allergic reaction to sulfites.

I understand that Option E is the most closest to the arg and touching the elements of the conclusion more closely.....However, if we negate the option D then that also destroys the argument although some elements makes D out of scope

Allegric reactions caused by other components or ingredients are irrelevant!
