Task: Answer the multiple choice question.
Query: Which drug has a -0.094\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COC(=O)Cn1nc(-c2ccc(C)cc2)c2ccccc2c1=O
b: Cn1c(=O)c2sccc2n2c(CCCC(=O)NCc3ccco3)nnc12
c: CC(=O)c1ccc(OC(C)C)c(CN2CCCCC2)c1.Cl
d: CCOc1ccc(NC(=O)COC(=O)Cc2ccc(S(=O)(=O)N3CCOCC3)s2)cc1
Answer: a. COC(=O)Cn1nc(-c2ccc(C)cc2)c2ccccc2c1=O
