Problem statement: Answer the multiple choice question.
Query: Which drug has a 9.547\% 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 CC(=O)O.CN1CCCC(CN2c3ccccc3Sc3ccccc32)C1
b CCN(CC)C(=O)C(C)OC(=O)COc1ccc(Cl)cc1C
c O=C1c2ccccc2C(=O)c2c1cccc2N1CCN(Cc2ccccc2)CC1
d O=CNCC(=O)NCCc1ccc(Cl)cc1
Answer: d. O=CNCC(=O)NCCc1ccc(Cl)cc1
