Task: Answer the multiple-choice question.
Query: Which drug has a 8.318\% 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, b, or c without using any other words.
Options:
[a] CC(NS(=O)(=O)c1ccccc1)C(=O)Nc1ccc2c(c1)OCCO2
[b] CCOc1ccc(N(C(=O)Nc2ccccc2)C2=NCCC2)cc1
[c] COc1ccc(Nc2nc(C)nc3sc4c(c23)CCC4)cc1O
Answer: b. CCOc1ccc(N(C(=O)Nc2ccccc2)C2=NCCC2)cc1
