Task: Answer the multiple-choice question.
Query: Which drug exhibits a 7.880\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCOC(=O)c1cnc2ccc(OCC)cc2c1NCc1cccnc1.Cl
[b] O=C(Nc1cccnc1)C1(F)C(F)(F)C(F)(F)C(F)(F)C(F)(F)C1(F)F
[c] COc1ccc([N+](=O)[O-])cc1N(CC(=O)N1CCN(Cc2ccccc2)CC1)S(C)(=O)=O
[d] Cc1cc(C)nc(Nc2ccccc2Cl)n1.Cl
Answer: b. O=C(Nc1cccnc1)C1(F)C(F)(F)C(F)(F)C(F)(F)C(F)(F)C1(F)F
