Task: Answer the multiple choice question.
Question: Which drug exhibits a -9.430% human ether-à-go-go related gene (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) COc1ccc(OC)c(/C=N/NC(=O)C(=O)N2CCCC2)c1
(b) CCC(=O)N1CCN(CCN=CC2=C(O)CC(c3cccs3)CC2=O)CC1
Answer: b. CCC(=O)N1CCN(CCN=CC2=C(O)CC(c3cccs3)CC2=O)CC1
