Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.340\% 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(CCC(=O)NCCc2ccc(OC)c(OC)c2)cc1
b: O=C(NCc1ccc2c(c1)OCO2)C1CCN(S(=O)(=O)c2ccc(F)cc2)CC1
c: COc1ccc(Cl)cc1NC(=O)CCN1C(=O)C2CC=CCC2C1=O
d: O=C(O)c1cc(N/N=C2/CC(c3ccccc3)Oc3ccccc32)ccc1Cl
Answer: d. O=C(O)c1cc(N/N=C2/CC(c3ccccc3)Oc3ccccc32)ccc1Cl
