Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 17.096\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a COc1cccc(C(=O)NCc2ccc(N3CCN(C(=O)OC(C)(C)C)CC3)cc2)c1
b CCOC(=O)/C(C#N)=C\c1cc(OC)c(OC)cc1[N+](=O)[O-]
c CS(=O)(=O)N(CC(=O)NCc1ccco1)Cc1ccc(Cl)cc1
Answer: b. CCOC(=O)/C(C#N)=C\c1cc(OC)c(OC)cc1[N+](=O)[O-]
