Task: Answer the multiple choice question.
Query: Which compound exhibits a 10.226\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) O=C(N/N=C/c1ccc(Br)o1)c1ccc2c(c1)OCCO2
b) NC1=C([N+](=O)[O-])C(c2ccc(F)cc2)C2=C(CCCC2=O)O1
c) O=C(Cn1cc2c(n1)CCCC2)NCCc1ccccc1
d) Cc1ccc(C)c(OCC(=O)Nc2ccccc2C(=O)NC2CC2)c1
e) Cc1ccc(CNC(=O)C(=O)NCCC2CCCCN2S(=O)(=O)c2cccs2)cc1
Answer: b. NC1=C([N+](=O)[O-])C(c2ccc(F)cc2)C2=C(CCCC2=O)O1
