Task: Answer the multiple choice question.
Question: Which drug has a -7.768\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] C=CCn1c(=S)[nH]c2nc3c(cc2c1=O)COC(C)(C)C3
[b] CC(=O)c1ccc(OCC(O)CN2CCN(CC(O)COc3ccc(C(C)=O)cc3)CC2)cc1
Answer: b. CC(=O)c1ccc(OCC(O)CN2CCN(CC(O)COc3ccc(C(C)=O)cc3)CC2)cc1
