Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 18.498\% 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 additional words.
Options:
a: CCOC(=O)CN1C(=O)N[C@@H](c2ccco2)C(C(C)=O)=C1C
b: O=C(NCc1ccccc1Cl)C1CCN(c2ncnc3c2nc2n3CCCCC2)CC1
c: COc1ccc(-c2cc(C(F)(F)F)c(C#N)c(SCC(=O)Nc3ccc(C)cc3)n2)cc1
Answer: a. CCOC(=O)CN1C(=O)N[C@@H](c2ccco2)C(C(C)=O)=C1C
