Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.696\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] CCN(CC)S(=O)(=O)c1ccc(N2CCCC2)c(NC(=O)c2nn(C)c(=O)c3ccccc23)c1
[b] COCCN1Cc2cccc(C(=O)Nc3cc(OC)ccc3OC)c2C1=O
[c] CCc1cccc(CC)c1-n1c(-c2cccnc2)n[nH]c1=S
[d] Cc1cc(C)n2ncc(/C(N)=N/OC(=O)Nc3ccc(Cl)cc3)c2n1
[e] CCOC(=O)CN1C(=O)N[C@@H](c2ccccc2)C(C(C)=O)=C1C
Answer: b. COCCN1Cc2cccc(C(=O)Nc3cc(OC)ccc3OC)c2C1=O
