Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.470\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(CN(CCc1ccccc1)S(=O)(=O)c1ccc(Br)cc1)N/N=C/c1ccc2c(c1)OCO2
[b] O=C(Nc1ccccc1[N+](=O)[O-])C1(c2ccccc2)CCOCC1
Answer: b. O=C(Nc1ccccc1[N+](=O)[O-])C1(c2ccccc2)CCOCC1
