Problem statement: Answer the multiple choice question.
Query: Which drug has a 19.496\% 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 CCOC(=O)c1cnc2c(-c3ccc(Cl)cc3)c(C)nn2c1N
b CC(OC(=O)c1ccc2noc(-c3ccccc3)c2c1)C(N)=O
c CCOc1ccc(N2CC(C(=O)Nc3ccc(S(=O)(=O)N4CCOCC4)cc3)CC2=O)cc1
Answer: a. CCOC(=O)c1cnc2c(-c3ccc(Cl)cc3)c(C)nn2c1N
