Problem statement: Answer the multiple choice question.
Query: Which drug has a 0.219\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) Cc1cc(=O)oc2cc(OCC(=O)OCC(=O)Nc3ccc(C(N)=O)cc3)ccc12
(b) O=C(Nc1cccc(Cl)c1)O/N=C\c1ccncc1
Answer: b. O=C(Nc1cccc(Cl)c1)O/N=C\c1ccncc1
