Problem statement: Answer the multiple choice question.
Question: Which drug has a 2.449\% 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: COc1ccc(OC)c(C(=O)CSc2nnnn2C)c1
b: CCCc1[nH]nc2c1C(c1ccc(OC)c(CSc3ccccn3)c1)C(C#N)=C(N)O2.CCO
c: O=[N+]([O-])c1ncccc1OCc1ccc(Br)cc1F
Answer: a. COc1ccc(OC)c(C(=O)CSc2nnnn2C)c1
