Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -0.714\% 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] CS(=O)(=O)Oc1ccc2c(c1)O/C(=C\C=C\c1ccccc1)C2=O
[b] c1coc(-c2nnc3sc(Cc4cccs4)nn23)c1
Answer: a. CS(=O)(=O)Oc1ccc2c(c1)O/C(=C\C=C\c1ccccc1)C2=O
