Task: Answer the multiple choice question.
Question: Which drug has a 12.767\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CC1CCN(CCC(=O)Nc2ccc3c(c2)CCC3)CC1
b: O=C(OCCCCN1C(=O)c2ccccc2C1=O)c1ccc(Br)o1
c: Cn1c(SCC(=O)N/N=C/C=C\c2ccccc2[N+](=O)[O-])nc2ccccc21
d: O=C(O)CSc1nnnn1-c1ccc2c(c1)OCCO2
e: COc1ccc(-n2nc(C(=O)NCC(=O)NCCCN3CCCCCC3)c3ccccc3c2=O)cc1Cl
Answer: b. O=C(OCCCCN1C(=O)c2ccccc2C1=O)c1ccc(Br)o1
