Task: Answer the multiple choice question.
Question: Which compound has a -27.121\% 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 O=C(CCN1C(=O)c2ccccc2S1(=O)=O)N1CCN(c2ccc(F)cc2)CC1
b COC(=O)C1=C(c2ccc3ccccc3c2)C[C@@H]2CC[C@H]1N2C(=O)N1CCCCC1
Answer: a. O=C(CCN1C(=O)c2ccccc2S1(=O)=O)N1CCN(c2ccc(F)cc2)CC1
