Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.826\% 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] Cc1cc(C)nc(/N=C(/NC(=O)Nc2ccc(Cl)c(Cl)c2)Nc2cccc(Cl)c2)n1
[b] O=C1C2C(C(=O)N1c1ccc3c(c1)OCO3)C1C=CC2C12CC2
[c] CN1CCN(/N=C/c2nc(-c3ccccc3Cl)n3ccccc23)CC1
Answer: b. O=C1C2C(C(=O)N1c1ccc3c(c1)OCO3)C1C=CC2C12CC2
