Task: Answer the multiple choice question.
Query: Which compound has a -0.896\% 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: CCN(CC)C(=O)CSc1nnc(-c2ccc(S(=O)(=O)N3CCOCC3)cc2)n1C
b: COc1ccc2oc(=O)c(C(=O)Oc3ccc(NC(C)=O)cc3)cc2c1
c: CS(=O)(=O)N1N=C(c2ccc3nccnc3c2)CC1c1ccccc1
Answer: b. COc1ccc2oc(=O)c(C(=O)Oc3ccc(NC(C)=O)cc3)cc2c1
