Task: Answer the multiple choice question.
Question: Which drug has a 10.048\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CNC(=S)N/N=C/c1cn(Cc2c(F)cccc2Cl)c2ccccc12
b CCCCCn1c(N)c(-c2nc3ccccc3o2)c2c([N+](=O)[O-])nn(C)c(=O)c21
Answer: b. CCCCCn1c(N)c(-c2nc3ccccc3o2)c2c([N+](=O)[O-])nn(C)c(=O)c21
