Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.138\% 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. COc1ccccc1N1CCN(C(CNS(=O)(=O)c2ccccc2)c2cccnc2)CC1
b. CCCCOc1ccc(-c2nnc(-c3cc[n+](C)cc3)o2)cc1.O=S(=O)([O-])c1ccccc1
c. CCOc1ccccc1N1CCN(CC(=O)NC(=O)NCc2ccco2)CC1
Answer: a. COc1ccccc1N1CCN(C(CNS(=O)(=O)c2ccccc2)c2cccnc2)CC1
