Task: Answer the multiple choice question.
Question: Which drug exhibits a -40.556% 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] CCNC(=S)N1CCN(CCN=CC2=C(O)CC(c3cccs3)CC2=O)CC1
[b] COC(=O)C1(CO)NC(c2ccc(C)cc2)C2C(=O)N(c3ccccc3)C(=O)C21
Answer: a. CCNC(=S)N1CCN(CCN=CC2=C(O)CC(c3cccs3)CC2=O)CC1
