Task: Answer the multiple choice question.
Query: Which compound has a 8.768\% 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: O=C(N/N=C/c1cc2c(cc1Br)OCO2)C1COc2ccccc2O1
b: O=C(NCc1ccccn1)c1cc2c(ccc3ccccc32)oc1=O
c: O=[N+]([O-])c1ccc(Cl)c(-c2ccc(/C=N/n3cnnc3)o2)c1
Answer: b. O=C(NCc1ccccn1)c1cc2c(ccc3ccccc32)oc1=O
