Task: Answer the multiple choice question.
Question: Which compound has a -65.889% human ether-à-go-go related gene (hERG) inhibition at 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(NCc1nc2ccccc2[nH]1)C1=C[C@@H](c2ccc(Br)cc2)C[C@@H](OCCCCO)O1
[b] Cc1sc(NC(=O)Cc2ccc3c(c2)OCO3)nc1-c1ccc2c(c1)CCN2C(=O)c1ccccc1F
[c] COc1ccc2c(c1)CCc1c(C(=O)N3CCOCC3)noc1-2
[d] CN1CCN(C(=S)C(=O)Nc2ccccc2)CC1
Answer: a. O=C(NCc1nc2ccccc2[nH]1)C1=C[C@@H](c2ccc(Br)cc2)C[C@@H](OCCCCO)O1
