Task: Answer the multiple-choice question.
Question: Which compound exhibits a 8.539\% 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: CCn1c(=O)cc(SCC(=O)NCCC2=CCCCC2)c2ccccc21
b: CSc1cccc(NC(=S)N(CCC(C)C)C2CCN(C(C)=O)CC2)c1
c: CNC(=S)SCCOc1ccc(C)cc1
d: S=c1[nH]c2ccc(Cl)cc2s1
Answer: d. S=c1[nH]c2ccc(Cl)cc2s1
