Task: Answer the multiple-choice question.
Question: Which compound exhibits a 0.675\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] N#C/C(=N\Nc1ccc(F)cc1)C(=N)N1CCCCC1
[b] C=CCc1c(C)nc2c(OC)cccc2c1Cl
[c] CCOC(=O)C/C(C)=N/NC(=O)CNc1cccc(Cl)c1C
Answer: b. C=CCc1c(C)nc2c(OC)cccc2c1Cl
