Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.456\% 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 additional words.
Options:
a) Cc1cccn2c(=O)c(C=Nc3ccc(Cl)cc3)c(NCCO)nc12
b) O=C1NCCCN1Cc1ccc(Cl)cc1
c) O=C(Nc1cccc([N+](=O)[O-])c1)C1COc2ccccc2O1
d) CC(NC1=NCCC1)c1ccc(F)cc1
Answer: b. O=C1NCCCN1Cc1ccc(Cl)cc1
