Task: Answer the multiple choice question.
Question: Which compound has a 14.053\% 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) CCc1cccc(CC)c1-n1c(-c2cccnc2)n[nH]c1=S
(b) O=C1N/C(=C\c2ccc(O)cc2)C(O)=C1C=NCc1ccccc1
Answer: b. O=C1N/C(=C\c2ccc(O)cc2)C(O)=C1C=NCc1ccccc1
