Task: Answer the multiple-choice question.
Query: Which drug has a -1.692\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a Cn1c(=O)oc2cc(S(=O)(=O)Nc3ccccc3C(=O)O)ccc21
b COc1ccc(C(=O)NCCn2cc(SCC(=O)Nc3cc(C)on3)c3ccccc32)cc1OC
c O=C(COc1ccccc1Br)N1CCN(C(=O)c2cccs2)CC1
d CC(=O)/C(=N/Nc1ccc([N+](=O)[O-])cc1)N1CCCc2ccccc21
e Cn1c(N)c(C(=O)CSc2nnc(C3CC3)n2N)c(=O)n(C)c1=O
Answer: c. O=C(COc1ccccc1Br)N1CCN(C(=O)c2cccs2)CC1
