Task: Answer the multiple-choice question.
Query: Which compound has a -1.474\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COc1ccccc1N(CC(=O)NCCSCc1ccccc1)S(C)(=O)=O
[b] O=C(NCc1ccccc1)C1=C[C@@H](C2CC2)C[C@@H](OCCCCO)O1
[c] O=C(CN1CCOCC1)n1c2ccccc2c2ccccc21
[d] COc1cccc(NC(=O)Cc2nc(-c3ccccc3)sc2-c2ccc(C)cc2)c1
Answer: c. O=C(CN1CCOCC1)n1c2ccccc2c2ccccc21
