Task: Answer the multiple-choice question.
Question: Which drug has a -49.308% 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: O=C(NCc1cccnc1)c1ccc(CS(=O)(=O)Cc2ccc(Cl)cc2)o1
b: COc1ccc(NS(=O)(=O)c2ccc(OCC(=O)N3CCN(C)CC3)cc2)cc1Cl
c: O=C(/C=C(\O)c1ccccc1)C(=O)NNC(=O)c1ccccc1[N+](=O)[O-]
d: CCOC(=O)C1CCN(C(=O)COC(=O)c2cc(-c3cccs3)nn2-c2ccccc2)CC1
Answer: d. CCOC(=O)C1CCN(C(=O)COC(=O)c2cc(-c3cccs3)nn2-c2ccccc2)CC1
