Task: Answer the multiple-choice question.
Question: Which drug has a 20.751% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. O=C1c2cccc3c(O)ccc(c23)C(=O)N1Cc1ccccc1
b. COc1ccc(-c2noc(-c3ccccc3F)n2)cc1
c. O=C(CNC(=O)c1ccc(Br)cc1)N/N=C/c1ccc[nH]1
Answer: c. O=C(CNC(=O)c1ccc(Br)cc1)N/N=C/c1ccc[nH]1
