Task: Answer the multiple choice question.
Question: Which drug exhibits a -10.533\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCCCCC(=O)Nc1cccc(C2=NOC3(C2)C[C@@H](C(N)=O)N(C(=O)c2ccc(OC)cc2)C3)c1
[b] O=C(Cn1cnc2c(cnn2-c2ccc(F)cc2)c1=O)N1CCCc2ccccc21
[c] Cc1c(Br)c([N+](=O)[O-])nn1CC(=O)NCc1cccnc1
[d] CC(=O)c1cccc(CN2CCC(C(=O)Nc3ccc(-c4cccc(C)c4)cc3)CC2)c1
Answer: b. O=C(Cn1cnc2c(cnn2-c2ccc(F)cc2)c1=O)N1CCCc2ccccc21
