Problem statement: Answer the multiple choice question.
Query: Which compound has a 0.865\% 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) CN(C[C@H](c1ccccc1)N(C[C@H](Cc1ccccc1)N(CCc1ccccc1)N=O)N=O)N=O.[Na+]
b) CC1CCc2c(sc3nc(CSc4n[nH]c(N)n4)[nH]c(=O)c23)C1
c) Cc1cc(C)n(S(=O)(=O)c2ccc(Cl)cc2)n1
d) CCn1ncc(/C=N\NC(=O)c2cc(-c3ccc(C)cc3C)nc3ccccc23)c1C
e) O=C(C1=COCCO1)N1CCN(S(=O)(=O)c2cccc(Br)c2)CC1
Answer: e. O=C(C1=COCCO1)N1CCN(S(=O)(=O)c2cccc(Br)c2)CC1
