Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.655\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C(Cc1cccc(Cl)c1)Nc1ccc(Br)cc1
[b] Cc1noc(C)c1S(=O)(=O)N1CCC(C(=O)NC2CCN(Cc3ccccc3)CC2)CC1
[c] Cc1[nH]n(-c2ccccc2)c(=O)c1C(C[N+](=O)[O-])c1ccc(Cl)cc1
Answer: a. O=C(Cc1cccc(Cl)c1)Nc1ccc(Br)cc1
