Task: Answer the multiple-choice question.
Question: Which compound has a 3.006\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(Cn1cc(C(F)(F)F)cc(Cl)c1=O)NC1CCS(=O)(=O)C1
b: COc1cc2c(c(OC)c1OC)-c1ccc(N(C)CC(OC)OC)c(=O)cc1[C@@H](NC(C)=O)CC2
c: CCOC(=O)Cn1c(=NC(=O)CSC(C)=O)sc2ccccc21
Answer: a. O=C(Cn1cc(C(F)(F)F)cc(Cl)c1=O)NC1CCS(=O)(=O)C1
