Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 13.749\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) Br.O=C(Nc1ccc(F)cc1)C1=CC(=O)N2CCN=C2S1
(b) N#CC1(NC(=O)COC(=O)c2nc(Cl)c(Cl)c(N)c2Cl)CCCCC1
Answer: a. Br.O=C(Nc1ccc(F)cc1)C1=CC(=O)N2CCN=C2S1
