Task: Answer the multiple choice question.
Query: Which compound has a -4.014\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COCCCNC(=O)C1=CCN(S(=O)(=O)c2ccc(C)cc2)CC1
[b] O=C(CSc1nc2ccccc2[nH]1)Nc1nc(-c2ccc(Br)cc2)cs1
[c] COc1ccc(/C=N/NC(=O)CNC(=O)c2ccncc2)cc1
[d] CC(C)OC(=O)CCCN1C(=O)c2ccc(N)cc2C1=O
Answer: a. COCCCNC(=O)C1=CCN(S(=O)(=O)c2ccc(C)cc2)CC1
