Task: Answer the multiple choice question.
Question: Which drug exhibits a 5.406\% 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 additional words.
Options:
a COCCCN1C(=O)C2C(C(=O)Nc3cccc(Cl)c3)C3C=CC2(O3)C1C(=O)NC1CCCCC1
b COC(=O)c1sccc1NC(=S)Nc1cccc(F)c1
Answer: a. COCCCN1C(=O)C2C(C(=O)Nc3cccc(Cl)c3)C3C=CC2(O3)C1C(=O)NC1CCCCC1
