Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 0.681% 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(C(=O)Nc2ccc(NC(=O)c3ccco3)c(Cl)c2)cc1OC
[b] C=CCn1c(O)c(C(CC)=NCCN2CCN(C(=S)NC)CC2)c(=O)[nH]c1=O
Answer: b. C=CCn1c(O)c(C(CC)=NCCN2CCN(C(=S)NC)CC2)c(=O)[nH]c1=O
