Task: Answer the multiple choice question.
Question: Which drug has a 15.665\% 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] COc1ccc2c(C=Nc3c(C)n(C)n(-c4ccccc4)c3=O)c(O)n(Cc3ccco3)c(=O)c2c1
[b] O=C(Nc1ccccc1)/C(=C/c1ccccc1)NC(=O)c1ccco1
[c] O=C(Cc1cccs1)Nc1ccc(S(=O)(=O)N2CCCC2)cc1
[d] O=C(CS(=O)(=O)c1cn(Cc2ccc(Cl)cc2)c2ccccc12)N1CCCCC1
[e] Cn1c(=O)c2cc(S(=O)(=O)Nc3cc(C(=O)O)cc(C(=O)O)c3)ccc2n(C)c1=O
Answer: b. O=C(Nc1ccccc1)/C(=C/c1ccccc1)NC(=O)c1ccco1
