Task: Answer the multiple-choice question.
Query: Which compound exhibits a -4.085\% 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. O=S(=O)(Nc1ccc2oc(-c3ccccc3)nc2c1)c1ccccc1
b. COC(=O)CC1=NN(c2ccc(OC)cc2)C(=O)/C1=C\c1ccc(Cl)cc1
c. CCOc1c(OC(C)=O)ccc(/C=C/c2ccc3cccc(OC)c3n2)c1[N+](=O)[O-]
d. COc1cc(C(c2nnnn2C(C)(C)C)N2CCN(C)CC2)cc(OC)c1OC
Answer: a. O=S(=O)(Nc1ccc2oc(-c3ccccc3)nc2c1)c1ccccc1
