Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 8.634\% human ether-à-go-go related gene (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) COc1ccc(/C=C/C(=O)Nc2cc(C)nn2-c2nc3ccccc3n2Cc2cccc([N+](=O)[O-])c2)cc1
(b) O=C(CCS(=O)(=O)c1ccc(Br)cc1)Nc1cc(F)ccc1F
Answer: b. O=C(CCS(=O)(=O)c1ccc(Br)cc1)Nc1cc(F)ccc1F
