Task: Answer the multiple choice question.
Question: Which compound exhibits a -0.714\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COC(=O)/C=c1/sc2n(c1=O)CCN=2
b: C[C@@H](C(=O)N[C@@H](Cc1ccccc1)C(=O)O)n1nnc2ccccc2c1=O
c: COC(=O)/C(=C1/Oc2ccc(C(C)(C)C)cc2S1)C(F)(F)F
d: O=C(Nc1ccc(N2CCOCC2)cc1)Nc1ccc(Cl)c(Cl)c1
e: CC(C)(C)c1ccccc1NC(=O)Cn1c(=O)cnc2ccccc21
Answer: e. CC(C)(C)c1ccccc1NC(=O)Cn1c(=O)cnc2ccccc21
