Task: Answer the multiple-choice question.
Question: Which drug has a 12.644\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a COc1ccc(CN2CCc3ccc(NC(=O)CCc4ccccc4OC)cc3C2)c(O)c1
b CCCN1CC=C2C(C#N)=C(N)C(C#N)(C#N)C(c3cccc(OC)c3OC)C2C1
c O=C(NCC(c1cccs1)N1CCOCC1)c1ccc(Cl)c([N+](=O)[O-])c1
d COc1ccc(/C=N/NC(=O)Cc2n[nH]c(=O)[nH]c2=O)cc1
e CCOC(=O)C1=C(c2ccccc2)NC(=O)NC1c1cc(OC)c(OC)c(OC)c1
Answer: d. COc1ccc(/C=N/NC(=O)Cc2n[nH]c(=O)[nH]c2=O)cc1
