Task: Answer the multiple choice question.
Query: Which drug has a 20.903\% 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: CC1=NN(Cc2ccccc2)C(=O)C1C(c1ccc(Cl)cc1)C(C#N)C#N
b: Cc1nc2cc(C(=O)NCCN3CCOCC3)ccc2n1-c1ccc(F)cc1F
c: CCCOc1ccc(C(=O)N(Cc2cccs2)C2CCS(=O)(=O)C2)cc1
d: O=C(O)COc1ccccc1/C=N/NC(=O)CSc1nc2ccccc2c(=O)n1-c1ccc(Cl)cc1
Answer: a. CC1=NN(Cc2ccccc2)C(=O)C1C(c1ccc(Cl)cc1)C(C#N)C#N
