Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.259\% 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 Cc1ccc2c(c1)CC1(CN2C)C(=O)NC(=O)N(c2cc(C)ccc2C)C1=O
b CCc1ccc(S(=O)(=O)Nc2ccc(O)c3c(=O)cc(-c4ccccc4Cl)oc23)cc1
Answer: a. Cc1ccc2c(c1)CC1(CN2C)C(=O)NC(=O)N(c2cc(C)ccc2C)C1=O
