Task: Answer the multiple-choice question.
Query: Which drug exhibits a -34.426% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a N/C(=N\OC(=O)Cc1ccccc1[N+](=O)[O-])c1cccc(Br)c1
b O=C(CSc1nc2ccccc2n1Cc1ccc(Cl)cc1)N/N=C/c1ccccc1C(=O)O
c Cn1c(=O)n(C)c2cc([N+](=O)[O-])c(N3CCN(C(=O)c4ccccc4Cl)CC3)cc21
d FC(F)(F)c1ccccc1-n1c(-c2ccco2)n[nH]c1=S
Answer: c. Cn1c(=O)n(C)c2cc([N+](=O)[O-])c(N3CCN(C(=O)c4ccccc4Cl)CC3)cc21
