Task: Answer the multiple-choice question.
Query: Which drug has a -0.010\% 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 additional words.
Options:
a. CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C21CCN(C(=O)OCc2ccccc2)CC1
b. CC1(C)CC(=O)C=C(c2cccc(O)c2)C1=O
c. C=CCN(C(=O)CCC(=O)Nc1cc(C)on1)C(C(=O)NC1CCCC1)c1ccc(OC)c(OC)c1
d. O=C(Cc1ccc(F)cc1)N1CCN=C1SCc1cccc([N+](=O)[O-])c1
Answer: a. CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C21CCN(C(=O)OCc2ccccc2)CC1
