Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -0.004\% 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] Nn1c(Cc2ccc(Br)cc2)n[nH]c1=S
[b] CCCN1CNC(=S)N(c2cccc(C)c2C)C1
Answer: b. CCCN1CNC(=S)N(c2cccc(C)c2C)C1
