Task: Answer the multiple choice question.
Question: Which compound has a 6.412\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1nc(-c2ccccc2)ccc1-c1noc(-c2cccnc2)n1
b: O=c1[nH]c2ccc(NS(=O)(=O)c3ccc([N+](=O)[O-])cc3)cc2[nH]1
c: CCN1CCN(c2nc3ccccc3nc2C(C#N)S(=O)(=O)c2ccc(C)c(C)c2)CC1
d: CS(=O)(=O)N(CC(=O)NCCSCc1c(F)cccc1Cl)c1ccc2c(c1)OCO2
Answer: b. O=c1[nH]c2ccc(NS(=O)(=O)c3ccc([N+](=O)[O-])cc3)cc2[nH]1
