Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a -4.372\% 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 other words.
Options:
a CCOC(=O)N1CCC(N2CCN(S(=O)(=O)c3ccc(C)cc3)CC2)CC1.O=C(O)C(=O)O
b CC(C)(C)c1ccc(-n2ncc3c2CCCC3NC(=O)CCn2cncn2)cc1
c C/C(CC(=O)Nc1ccc([N+](=O)[O-])cc1)=N\NC(=O)c1ccccc1[N+](=O)[O-]
d CC(C)OC(=O)c1cc2c(=O)[nH]c(C(Cl)(Cl)Cl)nc2o1
Answer: a. CCOC(=O)N1CCC(N2CCN(S(=O)(=O)c3ccc(C)cc3)CC2)CC1.O=C(O)C(=O)O
