Task: Answer the multiple-choice question.
Question: Which drug has a -1.683\% 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: COc1ccc(NC(=O)CN2C(=O)c3cccc4cccc2c34)c(OC)c1
b: COC(=O)c1sccc1NS(=O)(=O)c1ccc(OC)cc1
c: O=c1c(-c2ccc(Cl)cc2)c[nH]n1-c1ccccc1
Answer: b. COC(=O)c1sccc1NS(=O)(=O)c1ccc(OC)cc1
