Task: Answer the multiple choice question.
Query: Which drug has a 14.548\% 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] CC[N+](CC)(CCCCS(=O)(=O)[O-])CCNP1(=O)C=C(c2ccccc2)OC(c2ccccc2)=C1
[b] C=C(C)C(=O)Nc1ccc(NC(C)C)cc1
Answer: b. C=C(C)C(=O)Nc1ccc(NC(C)C)cc1
