Task: Answer the multiple choice question.
Question: Which drug exhibits a 10.607\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) O=S(=O)(c1ccc(Br)cc1)N1CCN(Cc2ccco2)CC1
(b) COCCNC(C(=O)Nc1ccc(C)cc1[N+](=O)[O-])c1ccccc1
Answer: a. O=S(=O)(c1ccc(Br)cc1)N1CCN(Cc2ccco2)CC1
