Task: Answer the multiple choice question.
Question: Which drug has a 21.908\% 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) CCS(=O)(=O)c1nc(S(=O)(=O)c2ccc(Cl)cc2)c(NCc2ccco2)s1
(b) N/C(=N\OC(=O)c1ccc(Br)cc1)c1cccc([N+](=O)[O-])c1
Answer: b. N/C(=N\OC(=O)c1ccc(Br)cc1)c1cccc([N+](=O)[O-])c1
