Task: Answer the multiple choice question.
Question: Which drug exhibits a 21.476% human ether-à-go-go related gene (hERG) inhibition at 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(Nc1ccc(N2CCCC2)cc1)c1ccc(Br)cc1
b O=C(COC(=O)COc1ccccc1F)Nc1ccc2c(c1)OCO2
c Cc1cc(NC2CCCC2)n2nc(C)c(-c3ccccc3)c2n1
d COc1ccc(NC(=O)C2OCCc3ccccc32)c(OC)c1
Answer: a. O=C(Nc1ccc(N2CCCC2)cc1)c1ccc(Br)cc1
