Task: Answer the multiple-choice question.
Query: Which drug has a 0.432% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(CCC1COc2ccccc2O1)Nc1ccc(Cl)cn1
b: COCCn1c(=O)c2c(nc3n2CCCN3CCc2ccc(OC)c(OC)c2)n(C)c1=O
c: COC(=O)c1cc(Br)c(=O)n(Cc2ccncc2)c1
d: CCCCS(=O)(=O)Nc1ccc(Cc2ccncc2)cc1
Answer: b. COCCn1c(=O)c2c(nc3n2CCCN3CCc2ccc(OC)c(OC)c2)n(C)c1=O
