Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.529\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) Cc1cc2c(c(=O)n1C)C(C(C)C)C(C#N)=C(N)O2
b) CCOC(=O)COc1ccc(S(=O)(=O)N2CCN(c3ccccc3)CC2)cc1
Answer: b. CCOC(=O)COc1ccc(S(=O)(=O)N2CCN(c3ccccc3)CC2)cc1
