Task: Answer the multiple choice question.
Question: Which drug has a 4.978\% 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: O=[N+]([O-])c1cc(S(=O)(=O)N2CCCC2)ccc1N/N=C/c1ccccn1
b: CCN(C(=O)COC(=O)c1cc2ccccc2cc1O)C1CCS(=O)(=O)C1
Answer: b. CCN(C(=O)COC(=O)c1cc2ccccc2cc1O)C1CCS(=O)(=O)C1
