Task: Answer the multiple-choice question.
Query: Which compound has a 20.897\% 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 additional words.
Options:
(a) CCOc1cc(NC(=O)c2ccco2)c(OCC)cc1NC(=O)COc1ccccc1
(b) COc1ccc(-c2csc(NC(=O)c3ccccc3F)c2C(=O)O)cc1
(c) O=C(NCn1cnccc1=O)c1ccccc1
Answer: c. O=C(NCn1cnccc1=O)c1ccccc1
