Task: Answer the multiple-choice question.
Question: Which compound exhibits a 2.162\% 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 additional words.
Options:
a: COc1ccc(/C=C2\N=C(C)N(c3ccc4ccccc4c3)C2=O)cc1OC
b: O=C(COC(=O)c1ccc2ncsc2c1)Nc1cccc(Cl)c1
c: CCOc1ccc(OCC)c(NC(=O)c2ccc(CNc3c(N4CCCC4)c(=O)c3=O)cc2)c1
Answer: a. COc1ccc(/C=C2\N=C(C)N(c3ccc4ccccc4c3)C2=O)cc1OC
