Task: Answer the multiple choice question.
Question: Which drug has a 10.833\% 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) NC(=S)Nc1nc2ccccc2[nH]c1=O
(b) O=C1NCCN1c1ccc(CN2CCN(C3CCCCC3)C(CCO)C2)cc1
(c) CCOc1ccccc1NC(=O)c1cc(S(=O)(=O)NCc2ccco2)ccc1F
(d) c1ccc2nc(OCCN3CC3)ccc2c1
Answer: a. NC(=S)Nc1nc2ccccc2[nH]c1=O
