Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.026\% 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) CCCCCC(=O)N/N=C/c1ccc(N(C)C)cc1
(b) Cc1ccc2nc(SCC(=O)N/N=C/c3ccco3)cc(C)c2c1
(c) O=c1[nH]c2ccc(S(=O)(=O)N3CCN(c4ccccc4)CC3)cc2[nH]c1=O
(d) C=CCNCCCCOc1ccc(OCc2ccccc2)cc1.O=C(O)C(=O)O
Answer: c. O=c1[nH]c2ccc(S(=O)(=O)N3CCN(c4ccccc4)CC3)cc2[nH]c1=O
