Task: Answer the multiple-choice question.
Query: Which compound exhibits a -1.469\% 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(CSc1nccc(=O)[nH]1)N1CCOCC1
b) Cc1cc(C)c2cc(CN(Cc3cccs3)Cc3nnnn3CC3CCCO3)c(=O)[nH]c2c1
c) COc1ccc(C(=O)CSc2nnc(CNc3ccc(C)cc3C)n2Cc2ccco2)cc1
Answer: a. O=C(CSc1nccc(=O)[nH]1)N1CCOCC1
