Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.799% 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 CCN(CCN1CCCC1)C(=O)C1CCC(=O)N(CCCN2CCOCC2)C1
b COc1ccc(/C(O)=C2\C(=O)C(=O)N(c3cc(C)on3)C2c2cccc(OC)c2OC)cc1C
Answer: a. CCN(CCN1CCCC1)C(=O)C1CCC(=O)N(CCCN2CCOCC2)C1
