Task: Answer the multiple choice question.
Question: Which compound has a -55.314% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a C=CCOC(=O)C1=C[C@H](c2ccc(Br)cc2)[C@@H](CCCO)[C@H](OCC)O1
b O=C(COC(=O)Cc1c(Cl)cccc1Cl)NCCC1=CCCCC1
Answer: a. C=CCOC(=O)C1=C[C@H](c2ccc(Br)cc2)[C@@H](CCCO)[C@H](OCC)O1
