Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.143\% 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) NC(=O)C1CCN(C(=O)COc2ccc(S(=O)(=O)NC3CCCC3)cc2)CC1
b) CC(C)(C)C1=CC=C(C(C)(C)C)C(=O)C1=O
Answer: b. CC(C)(C)C1=CC=C(C(C)(C)C)C(=O)C1=O
