Task: Answer the MCQ question.
Query: Which compound has a 24.489\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1ccccc1/C=C/C(=O)OCC(=O)Nc1ccc(Cl)cn1
b: COC(=O)C1=C(C)OC(N)=C(C#N)C1c1cc2cc(C)ccc2nc1Cl
c: CC(=O)Nc1ccc(/C=N/NC(=O)CNS(=O)(=O)c2ccccc2)cc1
Answer: b. COC(=O)C1=C(C)OC(N)=C(C#N)C1c1cc2cc(C)ccc2nc1Cl
