Problem statement: Answer the multiple choice question.
Question: Which drug has a 9.784\% 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: CCOC(=O)C1=C(COc2ccccc2)NC(=O)NC1c1cccc([N+](=O)[O-])c1
b: COc1cccc(NC(=O)COC(=O)c2ccccc2C(=O)N2CCN(c3ccccc3)CC2)c1
c: COc1ccc(C2=NOC(C(=O)NCc3ccco3)C2)cc1
d: Cn1cccc1C(=O)NC(=O)COC(=O)Cc1coc2ccc3ccccc3c12
Answer: a. CCOC(=O)C1=C(COc2ccccc2)NC(=O)NC1c1cccc([N+](=O)[O-])c1
