Task: Answer the multiple-choice question.
Query: Which compound exhibits a -3.365\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCOC(=O)N1CCN(C(=O)COC(=O)Cc2ccc(Cl)cc2)CC1
b: O=S(=O)(/N=C(/Nc1ccc(Cl)cc1Cl)c1ccccc1)c1cccs1
c: CC1(c2ccc(Cl)cc2Cl)OCC(Cn2cncn2)O1.O=[N+]([O-])O
d: CC(C(=O)NC1CCCC1)N1CCN(S(=O)(=O)c2ccc(C(C)(C)C)cc2)CC1
e: COc1ccc(Cl)cc1C(=O)NN=C1CCCC1
Answer: a. CCOC(=O)N1CCN(C(=O)COC(=O)Cc2ccc(Cl)cc2)CC1
