Task: Answer the multiple-choice question.
Query: Which compound exhibits a 3.345\% 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: O=C(NCc1ccc(F)cc1Cl)C1CCN(S(=O)(=O)N2CCC3(CC2)OCCO3)CC1
b: CCc1ccc(OCC(=O)OCC(=O)c2c(N)n(C)c(=O)n(C)c2=O)cc1
c: O=C(c1cc(C2CC2)on1)N1CCN(c2ccc(F)cc2)CC1
d: CC(C)c1csc(CN2CCC(CCC(=O)NCC3CCCO3)CC2)n1
e: O=C(/C(=N/N=C/c1ccc(O)c(O)c1)c1ccccc1)c1ccccc1
Answer: e. O=C(/C(=N/N=C/c1ccc(O)c(O)c1)c1ccccc1)c1ccccc1
