Problem statement: Answer the multiple choice question.
Query: Which drug has a -12.706\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: C=C(C)CN(CC)c1nc(N)c(C#N)c(CC#N)c1C#N
b: Cn1c(CSCc2ccc(Cl)cc2Cl)n[nH]c1=S
Answer: a. C=C(C)CN(CC)c1nc(N)c(C#N)c(CC#N)c1C#N
