Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 0.998\% 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.) CCN(CC)C(=O)Cc1cc(C(=O)O)c2ccccc2n1
b.) O=C(Cc1ccc(-n2c(=O)[nH]c3ccccc3c2=O)cc1)N1CCN(c2cccc(Cl)c2)CC1
Answer: b. O=C(Cc1ccc(-n2c(=O)[nH]c3ccccc3c2=O)cc1)N1CCN(c2cccc(Cl)c2)CC1
