Task: Answer the multiple choice question.
Query: Which compound has a -2.292\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) COC(=O)C1=C(C(=O)OC)C(c2cc(Cl)ccc2O)c2sc(=O)[nH]c2S1
b.) COc1cc(CCC(=O)Nc2ccc(Br)c(C(F)(F)F)c2)cc(OC)c1OC
c.) COc1ccc(NC(=O)c2nn(C)cc2[N+](=O)[O-])cc1
Answer: a. COC(=O)C1=C(C(=O)OC)C(c2cc(Cl)ccc2O)c2sc(=O)[nH]c2S1
