Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 15.300\% human ether-à-go-go related gene (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. Br.COc1ccc(C(=O)Cn2c(NCCCO)nc3ccccc32)cc1OC
b. CCO[C@H]1OC(C(=O)Nc2ccccc2)=C[C@@H](c2ccc(Br)cc2)[C@@H]1CCCO
c. CN(C)c1nc(Nn2cnnc2)nc(N(C)C)n1
Answer: b. CCO[C@H]1OC(C(=O)Nc2ccccc2)=C[C@@H](c2ccc(Br)cc2)[C@@H]1CCCO
