Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.482\% 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: COc1ccc(C2NC(=O)C(C#N)=C(S)N2c2ccc(C)cc2)cc1OC
b: Cc1ccc2c(cnn2C(=O)CCCC(=O)NCc2ccc(Cl)cc2)c1
c: CCc1cc2c(=O)c(-c3ccc4c(c3)OCCO4)c(C)oc2cc1OS(C)(=O)=O
Answer: a. COc1ccc(C2NC(=O)C(C#N)=C(S)N2c2ccc(C)cc2)cc1OC
