Task: Answer the multiple-choice question.
Query: Which compound has a 21.387\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) COc1ccccc1CNC(=O)[C@H](C)NC(=O)C1CC(=O)N(c2ccc3c(c2)OCO3)C1
b) O=C(Nc1cccc(Cl)c1)c1cccnn1
c) O=C(O)COc1ccc(/C=N/NC(=O)C(O)(c2ccccc2)c2ccccc2)cc1
Answer: c. O=C(O)COc1ccc(/C=N/NC(=O)C(O)(c2ccccc2)c2ccccc2)cc1
