Task: Answer the multiple choice question.
Query: Which compound has a 20.831\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. O=C(CCc1ccc(S(=O)(=O)NCc2ccccc2)cc1)NCc1ccco1
b. COc1ccc2oc(C(=O)NCC(c3ccco3)N(C)C)c(C)c2c1
c. COc1ccc(Cl)cc1C(=O)NNC(=O)CCNC(C)=O
Answer: c. COc1ccc(Cl)cc1C(=O)NNC(=O)CCNC(C)=O
