Task: Answer the multiple-choice question.
Question: Which compound exhibits a 10.302\% 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] COc1ccc(-n2nc(C(=O)NCC(=O)N3CCOCC3)c3ccccc3c2=O)cc1OC
[b] CC1=C(/C=C/C(C)=C/C=C/C(C)=C/C(=O)O)C(C)(C)CCC1
[c] CCOC(=O)C1=C(C)Nc2ncnn2C1c1cc(OC)ccc1OC
[d] O=C(Nc1ccc(O)cc1)/C(=C/c1ccco1)NC(=O)c1ccccc1
Answer: c. CCOC(=O)C1=C(C)Nc2ncnn2C1c1cc(OC)ccc1OC
