Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.383\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCCNC(=O)N1C2CCC1CC(O)(c1cccnc1)C2
(b) Cc1[nH]nc2c1C1(C(=O)Nc3ccc([N+](=O)[O-])cc31)C(C#N)=C(N)O2
Answer: b. Cc1[nH]nc2c1C1(C(=O)Nc3ccc([N+](=O)[O-])cc31)C(C#N)=C(N)O2
