Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.887\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) O=C(c1ccc(N2CCCC2=O)cc1)N1CCN(c2ccccc2)CC1
b) COc1ccc(S(=O)(=O)N2CC3CC(C2)c2cccc(=O)n2C3)cc1
Answer: a. O=C(c1ccc(N2CCCC2=O)cc1)N1CCN(c2ccccc2)CC1
