Task: Answer the multiple choice question.
Query: Which compound has a 25.021\% 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)N1C(=O)c1cc(F)c(F)cc1Cl
b.) O=C(COC(=O)c1cnccn1)c1ccc(Cl)cc1
c.) CCS(=O)(=O)Nc1cccc(C2=NN(S(=O)(=O)CC)C(c3cccs3)C2)c1
Answer: b. O=C(COC(=O)c1cnccn1)c1ccc(Cl)cc1
