Task: Answer the multiple choice question.
Question: Which drug has a 29.236\% 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) CCCCN(C)Cc1c(C)[nH]c2ccccc2c1=O
(b) CC(C)CCNC(=O)[C@H](CC(C)C)NC(=O)[C@H]1O[C@@H]1C(=O)O
Answer: b. CC(C)CCNC(=O)[C@H](CC(C)C)NC(=O)[C@H]1O[C@@H]1C(=O)O
