Task: Answer the multiple choice question.
Question: Which drug has a -1.889% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) O=C(CC1C(=O)NCCN1C(=S)Nc1ccccc1)Nc1ccc2c(c1)OCCO2
b.) CCC(=O)NC1=C(C#N)C2(CCCC2)Cc2ccccc21
Answer: b. CCC(=O)NC1=C(C#N)C2(CCCC2)Cc2ccccc21
