Task: Answer the multiple-choice question.
Query: Which drug exhibits a 7.755\% 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 additional words.
Options:
[a] O=C(CCN1CCOCC1)c1ccc(N2CCCCC2)cc1.[Br-]
[b] O=[N+]([O-])c1cccc(S(=O)(=O)NCCc2cn3ccccc3n2)c1
[c] COC(=O)C1(C(=O)OC)NOC2C(=O)N(N(C)c3ncc(C(F)(F)F)cc3Cl)C(=O)C21
[d] O=C(CC(=O)Nc1ccc(Br)cc1)Nc1ccc(Br)cc1
[e] CCCN=C(C)c1c(-c2ccccc2)[nH]n(-c2nc3ccccc3s2)c1=O
Answer: e. CCCN=C(C)c1c(-c2ccccc2)[nH]n(-c2nc3ccccc3s2)c1=O
