Task: Answer the multiple choice question.
Question: Which drug exhibits a 18.167\% 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) C=CCN(c1ccc(Cl)cc1)S(=O)(=O)c1cccc(C(=O)OCC(=O)N(C)C)c1
b) O=C(C1CCN(c2nnnn2-c2ccccc2)CC1)N1CCN(c2ccccc2)CC1
Answer: a. C=CCN(c1ccc(Cl)cc1)S(=O)(=O)c1cccc(C(=O)OCC(=O)N(C)C)c1
