Task: Answer the multiple choice question.
Query: Which drug has a 7.678\% 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)(c1ccc2ccccc2c1)N1CCN(S(=O)(=O)N2CCCCC2)CC1
b: CCN1CCN(CC(=O)Nc2ccc(C(C)=O)cc2)CC1.Cl
Answer: b. CCN1CCN(CC(=O)Nc2ccc(C(C)=O)cc2)CC1.Cl
