Task: Answer the multiple choice question.
Query: Which drug has a 11.764\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C1N[C@H](Cc2ccccc2)CO1
b) Cc1ccc2[nH]c(=O)c(CN(CCCN3CCOCC3)C(=O)Nc3ccc(Cl)cc3)cc2c1
c) COc1cccc(NC(=O)CSc2nc3c([nH]c4ccccc43)c(=O)n2C)c1
Answer: a. O=C1N[C@H](Cc2ccccc2)CO1
