Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.429\% 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: Cc1ccc(Nc2nc(N)c([N+](=O)[O-])c(NCCO)n2)cc1C
b: O=S(=O)(c1cccc(Cl)c1Cl)N1CCCCC1
Answer: b. O=S(=O)(c1cccc(Cl)c1Cl)N1CCCCC1
