Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.124\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CC(C)(C)c1nnc(SCC(=O)c2ccccc2)n(N)c1=O
[b] CCN1CCN(c2ccc(S(=O)(=O)N3CCOCC3)cc2NC(=O)c2cc(Cl)nc3ccccc23)CC1
Answer: a. CC(C)(C)c1nnc(SCC(=O)c2ccccc2)n(N)c1=O
