Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.948\% 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] O=C(O)c1cccc(-c2ccc(/C=N/Nc3nn[nH]n3)o2)c1
[b] CCc1noc(C)c1C(=O)Nc1sc(C(=O)N(C)C)c(C)c1C(=O)OC
[c] CN1CCN(C(=S)c2cn(Cc3ccc(Br)cc3)c3ccccc23)CC1
Answer: a. O=C(O)c1cccc(-c2ccc(/C=N/Nc3nn[nH]n3)o2)c1
