Task: Answer the multiple-choice question.
Query: Which drug has a -0.500\% 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 additional words.
Options:
a CC1CCN(S(=O)(=O)c2ccc(C(=O)N3CCCC(C(F)(F)F)C3)cc2)CC1
b O=[N+]([O-])c1ccc(C2C3C(c4ccccc4)=NC4(CCCC4)N32)cc1
c CC1=CC(=C(C#N)C#N)C=C(C)N1Cc1ccccc1
d CCOC(=O)c1ccc(NC(=S)N2CCN(C(=O)C3CCCO3)CC2)cc1
Answer: b. O=[N+]([O-])c1ccc(C2C3C(c4ccccc4)=NC4(CCCC4)N32)cc1
