Task: Answer the multiple-choice question.
Query: Which drug exhibits a 20.020\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. CC1CCCN(S(=O)(=O)c2ccc(NC(=O)C3CCN(C(=O)C(C)(C)C)CC3)cc2)C1
b. CCOc1ccccc1C(=O)OCC(=O)Nc1cc(Cl)ccc1Oc1ccccc1
c. O=C(c1cc(-c2cccc(O)c2)on1)N1CCOCC1
Answer: c. O=C(c1cc(-c2cccc(O)c2)on1)N1CCOCC1
