Task: Answer the multiple choice question.
Query: Which compound exhibits a 4.381\% human ether-à-go-go related gene (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] CCCCN(C(=O)CNC(=O)c1cccs1)C(C(=O)NC1CCCCC1)c1cccnc1
[b] Cc1c(NC(=O)c2c([N+](=O)[O-])cnn2C)c(=O)n(-c2ccccc2)n1C
[c] O=C(/C=C/c1ccccc1)N/C(=C/c1ccccc1)C(=O)Nc1ccccc1O
Answer: b. Cc1c(NC(=O)c2c([N+](=O)[O-])cnn2C)c(=O)n(-c2ccccc2)n1C
