Task: Answer the MCQ question.
Question: Which drug exhibits a 5.992\% 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=c1ccc2ccc(Oc3ccc([N+](=O)[O-])cc3Cl)cc2o1
(b) COCCN(C(=O)COC(=O)Cc1cccc(OC)c1)c1c(N)n(CC(C)C)c(=O)[nH]c1=O
(c) COc1ccc(CNCc2ccccc2[N+](=O)[O-])cc1OC.O=C(O)C(=O)O
(d) O=C(COC(=O)c1cccnc1)c1ccc(Br)cc1
Answer: c. COc1ccc(CNCc2ccccc2[N+](=O)[O-])cc1OC.O=C(O)C(=O)O
