Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 3.345\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) CCOC(=O)CNC=C(C(=O)OCC)C(=O)OCC
b) CC(=O)/C(C(=N)N1CCN(Cc2ccccc2)CC1)=C(\C)O
c) CCC(OC(=O)c1cc2sccc2n1C)C(=O)NCc1ccco1
Answer: a. CCOC(=O)CNC=C(C(=O)OCC)C(=O)OCC
