Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -4.140\% human ether-à-go-go related gene (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) O=C(CSc1nnc(CN2CCOCC2)n1-c1ccccc1)Nc1ccc(Cl)cc1
(b) COc1ccc(OCC(O)CN(CC(O)COc2ccc(OC)cc2)c2cccc(O)c2)cc1
(c) COc1ccc(OC)c(NC(=O)CCC(=O)Oc2ccc(C)cc2)c1
(d) CCc1cc2ccc(OC)cc2nc1SCC(=O)NNC(C)=O
Answer: a. O=C(CSc1nnc(CN2CCOCC2)n1-c1ccccc1)Nc1ccc(Cl)cc1
