Task: Answer the multiple choice question.
Query: Which compound exhibits a 12.012\% 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) CCOc1ccc2nc(CN3CCN(Cc4ccccc4OCC)C(CCO)C3)ccc2c1
(b) COc1ccc(-c2nn(C)c(=O)c3ccccc23)cc1CNC(=O)C1CCCCC1
(c) O=S(=O)(c1cc(Cl)ccc1Cl)N1CCNCC1
Answer: c. O=S(=O)(c1cc(Cl)ccc1Cl)N1CCNCC1
