Problem statement: Answer the multiple-choice question.
Query: Which drug has a -0.730% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CC1(c2nnc(Cc3ccccc3)o2)CC(c2ccc(C#N)cc2)=NO1
[b] O=C(Nc1ccccc1F)Nc1ccccc1OC(F)F
[c] c1ccc(Cn2nnc3c(NCCN4CCOCC4)ncnc32)cc1
[d] CCOC(=O)C1=C(C)NC(=O)NC1c1cc(Br)c(O)c(OC)c1
Answer: b. O=C(Nc1ccccc1F)Nc1ccccc1OC(F)F
