Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.405\% 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: COc1cccc(C(=O)Nc2nnc(SCC(=O)Nc3ccc(NC(C)=O)cc3)s2)c1
b: O=C(CNC(=O)c1ccccc1)OCc1nc2ccccc2s1
c: CCC(C)C1=CC(=Nc2c(C)n(C)n(-c3ccccc3)c2=O)C=C(C(C)CC)C1=O
d: O=c1nccc(Nc2ccccc2)[nH]1
Answer: d. O=c1nccc(Nc2ccccc2)[nH]1
