Task: Answer the multiple choice question.
Question: Which drug has a 12.321\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. COc1ccc(C2=NN(C(=O)CSc3nc4ccccc4s3)C(c3ccc(F)cc3)C2)cc1
b. COc1cccc(N2C(=O)CC(N3CCN(C(=O)c4ccco4)CC3)C2=O)c1
c. COc1ccc(N2C(=O)C(Cl)=C(Oc3cccc(OC)c3)C2=O)cc1
d. COC(=O)c1c(-c2ccccc2)c[nH]c1C
Answer: d. COC(=O)c1c(-c2ccccc2)c[nH]c1C
