Task: Answer the multiple choice question.
Query: Which compound has a 7.887% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. O=C(Nc1ccc(Cl)c(Cl)c1)C1=Cc2ccccc2OC1
b. COc1ccc(NC(=O)CN2CCN(CC(=O)Nc3ccc4c(c3)OCO4)CC2)cc1
c. COc1cc(OC)c2c(-c3ccccc3)cc(=O)oc2c1C(CCN1CCN(c2ccccc2)CC1)c1ccc(N(C)C)cc1
d. O=S(=O)(NC1CCCC1)OCC(Cl)(Cl)Cl
Answer: c. COc1cc(OC)c2c(-c3ccccc3)cc(=O)oc2c1C(CCN1CCN(c2ccccc2)CC1)c1ccc(N(C)C)cc1
