Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 19.789\% 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) O=C(Nc1ccc(F)cc1)N1CCOCC1
(b) CC1CCN(c2c(NCc3ccc(C(=O)N(C)C4CCCCC4)cc3)c(=O)c2=O)CC1
(c) CCC(C)NC(=O)Cn1nc([N+](=O)[O-])c(Cl)c1C
Answer: a. O=C(Nc1ccc(F)cc1)N1CCOCC1
