Problem statement: Answer the multiple choice question.
Query: Which drug has a -1.309\% 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) O=C(Nc1ccc(N2CCOCC2)cc1)Nc1ccc2nsnc2c1
(b) COc1ccc2occ(C(=O)c3ccccc3)c2c1
(c) COc1cccc(-c2nc(C(N)=O)c3[nH]c(=O)n(-c4cccc(Cl)c4)c3n2)c1OC
Answer: b. COc1ccc2occ(C(=O)c3ccccc3)c2c1
