Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.535\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CCn1c(SCc2ccc(Cl)c(Cl)c2)nnc1C(C)NC(=O)c1ccc(OC)cc1
b: COC(C/C=C\C(=O)[C@H](C)OCc1ccccc1)OC
c: CCCN(CC(=O)Nc1ccc(Cl)cc1Cl)C(=O)CC(NC(C)=O)c1ccccc1
Answer: b. COC(C/C=C\C(=O)[C@H](C)OCc1ccccc1)OC
