Task: Answer the multiple choice question.
Question: Which drug has a 8.814\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CN1CCN(Cc2ccccc2C(F)(F)F)CC1
b CC(=O)c1c(C(C)=O)c(C)n(-c2ccc3ncccc3c2)c1C
c CC(=O)Nc1ccc(S(=O)(=O)Nc2nc3ccccc3nc2Nc2ccc(S(N)(=O)=O)cc2)cc1
d CCc1ccc(NS(=O)(=O)c2cccs2)cc1
Answer: a. CN1CCN(Cc2ccccc2C(F)(F)F)CC1
