Task: Answer the multiple choice question.
Question: Which drug has a 6.481% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CC1=CCC2([N+](=O)[O-])CN(CC(=O)O)CC1([N+](=O)[O-])C2
b Cn1c(=O)c2c(nc(-n3ccnc3)n2C)n(C)c1=O
c CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)[C@@H]2c1ccccc1[N+](=O)[O-]
d CCOc1cc(CN2CCCC(CO)(Cc3ccc(F)cc3F)C2)ccc1OC
Answer: b. Cn1c(=O)c2c(nc(-n3ccnc3)n2C)n(C)c1=O
