Problem statement: Answer the multiple choice question.
Question: Which compound has a -1.929\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] CCC(c1nnnn1C(C)(C)C)N(Cc1cccs1)Cc1cc2cc(C)c(C)cc2n2nnnc12
[b] CC(=O)Nc1ccc(C(=O)OCC(=O)Nc2ccccc2Sc2ccccc2)cc1
[c] COc1cccc(C(=O)NC(C)C(c2cccs2)N2CCN(C)CC2)c1
[d] CCN(CC)CCCN=C(C)C1=C(O)c2ccccc2C1=O
[e] O=C(CSC1c2ccccc2C(=O)N1c1ccccc1)N1CCOCC1
Answer: d. CCN(CC)CCCN=C(C)C1=C(O)c2ccccc2C1=O
