Problem statement: Answer the MCQ question.
Query: Which compound exhibits a 6.748\% 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=C1CCC[C@@H]2[C@H]3CCC[N+]4([O-])CCC[C@@H](CN12)[C@@H]34
[b] O=C(Nc1ccccc1-c1nc2ccccc2s1)C1=COCCO1
[c] CC1(C)CC(=O)C2=C(C1)N(Cc1ccco1)C(=O)NC2(C(F)(F)F)C(F)(F)F
[d] Cc1cccn2cc(-c3cccc(S(=O)(=O)N4CCOCC4)c3)nc12
[e] O=C(Nc1ccc(F)cc1F)Nc1ccc(F)cc1F
Answer: e. O=C(Nc1ccc(F)cc1F)Nc1ccc(F)cc1F
