Task: Answer the multiple choice question.
Question: Which compound exhibits a -2.469\% 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 additional words.
Options:
[a] Cc1ccc(-c2cc(C(=O)N/N=C/c3ccco3)[nH]n2)cc1
[b] C=CCOc1ccccc1C1NC(=O)NC(C)=C1C(=O)NCc1ccccc1
[c] Cc1cc(N(C)C)cc(C)[n+]1[O-]
[d] COc1ccc(C(=O)Nc2ccc3nc(C)sc3c2)cc1OC
Answer: b. C=CCOc1ccccc1C1NC(=O)NC(C)=C1C(=O)NCc1ccccc1
