Task: Answer the multiple-choice question.
Query: Which drug has a 8.572\% 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: C=CCOC(=O)C1=C(C)NC(=O)NC1/C=C/c1ccccc1
b: CC(C)(C)c1ccc(C(=O)NCC(=O)OCc2ccc([N+](=O)[O-])cc2)cc1
c: NC(=O)COc1cccc2cccnc12
d: COc1ccccc1N1CSC2=C(C#N)C(c3ccc(SC)cc3)CC(=O)N2C1
Answer: a. C=CCOC(=O)C1=C(C)NC(=O)NC1/C=C/c1ccccc1
