Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 13.009\% 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) O=C1NC(=S)CN1c1ccccc1
(b) CCCOc1ccc(N2C(=O)CC(N(Cc3ccco3)C(C)=O)C2=O)cc1
(c) N#CC(C#N)=Cc1cn(-c2ncc(C(F)(F)F)cc2Cl)c2ccccc12
Answer: a. O=C1NC(=S)CN1c1ccccc1
