Task: Answer the multiple-choice question.
Question: Which drug exhibits a -13.775% 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.) CCOC(=O)c1cc(-c2ccccc2)n(CCC(=O)N2CCN(c3ccc(OC)cc3)CC2)c1C
b.) CCCCC(=O)Nc1cccc(NC(=O)CC)c1
c.) Cc1cccc(C)c1NC(=O)Cn1nc(-c2ccc(Cl)s2)ccc1=O
d.) O=C(C/C=N\OCc1ccc([N+](=O)[O-])cc1)Nc1ccc(Cl)cc1
Answer: d. O=C(C/C=N\OCc1ccc([N+](=O)[O-])cc1)Nc1ccc(Cl)cc1
