Task: Answer the multiple-choice question.
Question: Which compound has a 5.121\% 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=C(CC(C(=O)O)C1CCCO1)Nc1cccc(C(F)(F)F)c1
[b] CC(C)NC(=O)CCn1nc(-c2ccccc2)ccc1=O
[c] S=C(NCc1ccc(Cl)cc1)NC1CCCCC1
Answer: b. CC(C)NC(=O)CCn1nc(-c2ccccc2)ccc1=O
