Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.578\% 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: CCN(CC(=O)NCc1ccc(F)cc1)Cc1nc2cc(Cl)ccc2c(=O)[nH]1
b: CCN1CCN(C(=O)c2ccc3c(=O)n(C4CCCC4)c(=S)[nH]c3c2)CC1
c: CN(C(=O)c1ccc(N2CCCCC2)c([N+](=O)[O-])c1)C1(C)CCS(=O)(=O)C1
d: CCc1nn(CC(=O)NCCCN2CCOCC2)c(=O)c2cc3cc(F)ccc3n12
e: O=C(N[C@@H](Cc1ccc(Br)cc1)C(=O)O)OCC1c2ccccc2-c2ccccc21
Answer: e. O=C(N[C@@H](Cc1ccc(Br)cc1)C(=O)O)OCC1c2ccccc2-c2ccccc21
