Task: Answer the multiple-choice question.
Question: Which drug has a -0.993% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) CC(C)(C)C1=CC(=O)C(N2CCOCC2)=CC1=O
b) O=C(NCc1ccccc1)C1=C[C@@H](c2csc3ccccc23)C[C@@H](OCCCCO)O1
c) CCCNC(=O)C(Cc1ccccc1)NC(=O)Cc1ccccc1
d) CN(C)C(=O)[C@@H]1C[C@H]1[C@@H](NC(=O)OCc1ccccc1)c1ccccc1
Answer: a. CC(C)(C)C1=CC(=O)C(N2CCOCC2)=CC1=O
