Task: Answer the multiple choice question.
Question: Which drug exhibits a -47.577\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CC(=O)NCCSC(=O)c1ccc(F)cc1
[b] CCC(C)/C(C)=N/NC(=O)CNS(=O)(=O)c1ccc([N+](=O)[O-])cc1
[c] COc1ccc(N2CCc3c(C)nc4c(OC)cc(OC)cc4c32)c(OC)c1
[d] C=CCn1c(=O)c2c(nc(Br)n2Cc2ccccc2Cl)n(C)c1=O
Answer: c. COc1ccc(N2CCc3c(C)nc4c(OC)cc(OC)cc4c32)c(OC)c1
