Task: Answer the multiple choice question.
Question: Which drug exhibits a 10.224\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CNC(=O)c1[nH]cnc1C(=O)Nc1cccc(OC)c1
b) NC(=O)CC(NC(=O)Cc1cccc2ccccc12)c1ccc(N2CCCCCCC2)c([N+](=O)[O-])c1
c) CCOc1ccccc1N(C(=O)Cn1nnnc1-c1ccc(C)o1)C(CC)C(=O)NC(C)(C)C
Answer: a. CNC(=O)c1[nH]cnc1C(=O)Nc1cccc(OC)c1
