Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.681\% 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. O=[N+]([O-])C(=C1Nc2ccccc2N1)/C(Cl)=C(/Cl)Br
b. COc1ccc(C(c2nnnn2Cc2ccccc2)N2CCN(c3nc4ccccc4s3)CC2)cc1OC.Cl
c. CCOc1ccc(C(N)=O)cc1OC
d. Cc1cc(C(C)(C)C)ccc1NC(=O)CC(C)(C)CC(=O)O
e. COc1ccc(C(C)=O)cc1COc1ccc([N+](=O)[O-])c(C)c1
Answer: b. COc1ccc(C(c2nnnn2Cc2ccccc2)N2CCN(c3nc4ccccc4s3)CC2)cc1OC.Cl
