Task: Answer the multiple-choice question.
Question: Which drug exhibits a -13.555\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(Nc1nnc(-c2ccc(Cl)cc2)o1)c1cccc(N2C(=O)CCC2=O)c1
b O=C(NCCc1c[nH]c2ccccc12)/C(=C\c1ccco1)NC(=O)c1ccco1
c Brc1nnc2n1-c1ccccc1Sc1ccccc1-2
d COc1ccc([N+](=O)[O-])c(OC)c1C(=O)NC(=O)Nc1nc(C)cc(C)n1
Answer: c. Brc1nnc2n1-c1ccccc1Sc1ccccc1-2
