Task: Answer the multiple choice question.
Query: Which drug has a 13.250\% 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, c, or d without using any other words.
Options:
(a) COc1ccccc1C(=O)NNC(=O)c1ccc(NC(=O)c2ccccc2)cc1
(b) Cc1ccc(-c2noc(COc3ccccc3C)n2)cc1
(c) COc1ccc([N+](=O)[O-])cc1-n1cccc1
(d) C=CCOc1ccc(CN(C)C(=O)CN2C(=O)c3ccccc3C2=O)cc1
Answer: b. Cc1ccc(-c2noc(COc3ccccc3C)n2)cc1
