Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -63.862\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] CC1=[N+]([O-])C(C)(C)C(C)N(O)C1=O
[b] O=C(COc1ccc(Cl)cc1Cl)NCCCCc1ccccc1
[c] C=CCn1c(SCCN2CCCC2)nc2c([nH]c3ccccc32)c1=O
[d] COc1ccc(OC(=O)C2CC(=O)N(c3ccc(C)cc3)C2)cc1
Answer: c. C=CCn1c(SCCN2CCCC2)nc2c([nH]c3ccccc32)c1=O
