Task: Answer the multiple-choice question.
Question: Which compound has a 12.390\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CCOc1ccc(/C(O)=C2/C(=O)C(=O)N(c3ncccn3)C2c2ccc(C)cc2)cc1
(b) O=C(O)CC(NCc1ccco1)C(=O)OCCCl
(c) Cc1ccc(C(=O)CCC(=O)OCC(=O)NNC(=O)c2ccc([N+](=O)[O-])cc2)cc1
(d) COc1ccccc1/C=C/C(C)=O
Answer: d. COc1ccccc1/C=C/C(C)=O
