Task: Answer the multiple choice question.
Question: Which drug has a 4.735\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Cc1cccc(C)c1NC(=O)C(=O)c1cn(C)c2ccccc12
b: O=C(Nc1cccc(C(F)(F)F)c1)C(Sc1cccc[n+]1[O-])c1ccccc1
c: CCc1ccc(C2C(C#N)=C(N)N(N3CCOCC3)C3=C2C(=O)CC(C)(C)C3)s1
Answer: b. O=C(Nc1cccc(C(F)(F)F)c1)C(Sc1cccc[n+]1[O-])c1ccccc1
