Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.981\% 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 additional words.
Options:
a: Cc1c(C(=O)Nc2ccc(N3CCOCC3)cc2)cccc1[N+](=O)[O-]
b: CN(C)S(=O)(=O)c1ccc(NC(=O)c2ccc3ncsc3c2)cc1
c: COc1ccc(N(Cc2cc(=O)[nH]c3ccccc23)C(=O)C(C)C)cc1
d: O=C1CN(C(=O)CSc2nnnn2-c2ccc(Cl)cc2)c2ccccc2N1
Answer: d. O=C1CN(C(=O)CSc2nnnn2-c2ccc(Cl)cc2)c2ccccc2N1
