Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.240\% 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.) COc1ccc(NC(=O)C(=O)NCC(c2ccco2)N2CCc3ccccc3C2)cc1OC
b.) CCN(CC)S(=O)(=O)c1c(OC)cc(C)c(Cl)c1C
Answer: b. CCN(CC)S(=O)(=O)c1c(OC)cc(C)c(Cl)c1C
