Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.393\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] Fc1cccc(Cl)c1-c1nnc2ccc(C(F)(F)F)cn12
[b] CN(C)c1ccc(NC(=O)c2cccc(N3C(=O)C4C5C=CC(C5)C4C3=O)c2)cc1
[c] CCOc1ccc(C2NC(=S)NC3=C2CCc2ccccc23)cc1
[d] CC(C)c1c(CN(C)C(C)Cc2ccccc2)n(C)n(-c2ccccc2)c1=O
Answer: c. CCOc1ccc(C2NC(=S)NC3=C2CCc2ccccc23)cc1
