Problem statement: Answer the multiple choice question.
Query: Which compound has a 2.642% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CCc1nc(NCc2cccnc2)c2oc3ccccc3c2n1.Cl
b: CCOC(=O)c1c(NC(=O)C2CCCO2)sc(C(N)=O)c1C
c: COc1ccccc1NC(=O)c1cc2n(n1)C(C(F)(F)F)CC(c1ccc3c(c1)OCO3)N2
Answer: b. CCOC(=O)c1c(NC(=O)C2CCCO2)sc(C(N)=O)c1C
