Task: Answer the multiple choice question.
Query: Which compound has a 4.622\% 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, c, or d without using any other words.
Options:
a: COCC(=O)Nc1ccc(OC)c(Cl)c1
b: COc1ccc(CNC(=O)CSc2ccsc2[N+](=O)[O-])cc1
c: COc1ccc(C(=O)Nc2ccc3c(c2)OCO3)cc1OC
d: O=c1c2c(nc3c(-c4cccc(Br)c4)c[nH]n13)CCCC2
Answer: d. O=c1c2c(nc3c(-c4cccc(Br)c4)c[nH]n13)CCCC2
