Task: Answer the multiple-choice question.
Question: Which drug exhibits a 16.880\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(O)c1ccc(-n2ncc3c2/C(=C/c2cccc([N+](=O)[O-])c2)CC3)cc1
[b] Cc1nn(C(=O)N2CCOCC2)c(C)c1C
Answer: a. O=C(O)c1ccc(-n2ncc3c2/C(=C/c2cccc([N+](=O)[O-])c2)CC3)cc1
