Task: Answer the multiple choice question.
Query: Which compound exhibits a 8.447\% 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] O=C(O)C1=C[C@@H](C2CCCCC2)C[C@@H](OCCCCO)O1
[b] O=C(O)CCCC(=O)NNC(=O)c1cccc(Br)c1
[c] O=C(COc1cc(F)ccc1[N+](=O)[O-])Nc1ccc(N2CCCCC2)cc1
[d] CCC12CN(C(=O)c3ccc([N+](=O)[O-])cc3)CC(CC)(CN(C(=O)c3ccc([N+](=O)[O-])cc3)C1)C2=O
Answer: a. O=C(O)C1=C[C@@H](C2CCCCC2)C[C@@H](OCCCCO)O1
