Task: Answer the multiple-choice question.
Question: Which compound exhibits a 8.659\% human ether-à-go-go related gene (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 additional words.
Options:
[a] Cc1cc(C)nc(NC(=O)c2cc(-c3ccc4c(c3)OCO4)nc3ccccc23)c1
[b] CC(C)(Oc1ccc(Cl)cc1)C(=O)Nc1ccncc1
[c] CC1Cc2ccccc2N1C(=S)NC(=O)c1cccc(Br)c1
[d] CCC1SC2=NC(C)=C(C(=O)OC)C(c3ccc(C(=O)OC)cc3)N2C1=O
Answer: d. CCC1SC2=NC(C)=C(C(=O)OC)C(c3ccc(C(=O)OC)cc3)N2C1=O
