Task: Answer the multiple choice question.
Query: Which drug has a 7.663\% 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] COc1ccc(C(=O)N[C@H](C(=O)NCc2cccs2)C(C)C)cc1
[b] Cn1c(=O)cc(N2CCN(C(=O)c3ccco3)CC2)[nH]c1=O
[c] COc1cccc(-c2c(C(=O)N/N=C(\C)c3ccncc3)nnn2-c2nonc2N)c1
[d] C=C(c1ccccc1)[n+]1cccc(C(=O)O)c1.[Br-]
Answer: b. Cn1c(=O)cc(N2CCN(C(=O)c3ccco3)CC2)[nH]c1=O
