Task: Answer the multiple choice question.
Question: Which drug has a -3.090\% 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 CC1CN(C(=O)CCC(=O)N2CCOCC2)c2ccccc2O1
b CC(=O)C(Cc1ccccc1)NC(=O)COC(=O)CCN1C(=O)C2CC=CCC2C1=O
c COc1ccc(S(=O)(=O)N(C)CC(=O)NCCCn2ccnc2)cc1Cl
d O=C(/C=C/c1ccccc1[N+](=O)[O-])Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1
Answer: a. CC1CN(C(=O)CCC(=O)N2CCOCC2)c2ccccc2O1
