Task: Answer the multiple choice question.
Query: Which compound exhibits a 11.279% 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) CCOC(=O)C(=O)N/N=C/c1ccco1
b) COc1ccc(Cc2nc3ccc(C(=O)N4CCN(C)C(C)C4)cc3o2)cc1OC
c) COc1cc(CNCCO)cc(Br)c1OCc1ccccc1.Cl
d) COc1ccc(NC(=O)CCC(=O)N/N=C/c2ccc([N+](=O)[O-])s2)cc1
Answer: a. CCOC(=O)C(=O)N/N=C/c1ccco1
