Task: Answer the multiple choice question.
Question: Which compound has a 5.397\% 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: O=C(Nc1ccc(N2CCOCC2)c(Cl)c1)c1ncn[nH]1
b: COC(=O)Cc1ccc(O)c(N)c1
c: O=C(CCCN1C(=O)/C(=C/c2ccco2)SC1=S)Nc1ccccc1C(=O)O
d: CCS(=O)(=O)N1CCC(C(=O)NCc2cccs2)CC1
Answer: d. CCS(=O)(=O)N1CCC(C(=O)NCc2cccs2)CC1
