Task: Answer the multiple-choice question.
Query: Which drug exhibits a -11.923\% 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 other words.
Options:
a COc1ccc(NC(=O)c2ccc(NCCN3C(=O)CCC3=O)c([N+](=O)[O-])c2)cc1
b Cc1occc1-c1nnc(SCC(=O)Nc2ccccc2-c2ccccc2)n1C
c CN1CCC(=C2c3ccccc3CCc3sccc32)CC1.O=C(O)/C=C\C(=O)O
d CCOC(=O)/C(C#N)=C1/C=CN(Cc2ccccc2)C=N1
Answer: d. CCOC(=O)/C(C#N)=C1/C=CN(Cc2ccccc2)C=N1
