Nope, D is out not for "bread" but for the use of plural verb.

please see the sentence as follows:

D. Consumption of bread made from ergot-infected grains often triggers severely debilitating symptoms such as muscle contractions, seizures and gangrene but, at a proper dose, also cause a significant reduction in

==> Consumption triggers but also cause(s).

Here, the subject of the two verbs--trigger and cause--is consumption, so both of the verbs MUST be in singular form.

Thanks.

What's the OA ?

OA C

The primary issue with this question is subject-verb agreement. The subject is "consumption,"
which is singular (and note that "consumption" is not underlined, so the subject will
be singular in the correct answer). Any verbs associated with this subject, therefore, also
must be singular. In the original sentence, they are both plural ("trigger" and "cause").

(A) This choice is incorrect because it repeats the original sentence.

(B) Although this sentence makes two changes from the original sentence, neither one
fixes the subject-verb agreement problem; the singular subject, "consumption," is still paired
with two plural verbs, "trigger" and "cause."

(C) CORRECT. This choice correctly pairs the singular subject, "consumption," with two
singular verbs, "triggers" and "causes."

(D) This sentence corrects the first of the two verbs ("triggers") by making it singular to match
the singular subject, "consumption," but the second verb ("cause") is still plural.

(E) This sentence corrects the second of the two verbs ("causes") by making it singular to
match the singular subject, "consumption," but the first verb ("trigger") is still plural.
