Task: Answer the multiple choice question.
Query: Which compound has a 9.539\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COC(=O)C(Cc1ccccc1)NC(=O)C(CC(C)C)NC(=O)OC(C)(C)C
b: CS(=O)(=O)N1CCN(C(=O)c2cc(-c3cccnc3)nc3ccc(Cl)cc23)CC1
c: CSc1nc2ccccc2cc1/C=C(\C#N)c1cccc(Cl)c1
d: O=c1[nH]c2nc(SCc3ccccc3)ncc2c(=O)n1-c1ccc(Cl)cc1
Answer: d. O=c1[nH]c2nc(SCc3ccccc3)ncc2c(=O)n1-c1ccc(Cl)cc1
