Task: Answer the multiple-choice question.
Query: Which drug exhibits a 8.689\% 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] N=C(N)N1CCN(Cc2ccccc2)CC1.O=S(=O)(O)O
[b] COC(=O)c1ccccc1NC(=O)C1CCCN(S(C)(=O)=O)C1
Answer: b. COC(=O)c1ccccc1NC(=O)C1CCCN(S(C)(=O)=O)C1
