Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.949\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] COCc1nnc(NC(=O)CC(C)C)s1
[b] Cc1cccc(N/C=C/c2onc(C)c2[N+](=O)[O-])c1
Answer: b. Cc1cccc(N/C=C/c2onc(C)c2[N+](=O)[O-])c1
