Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.775\% 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, d, or e without using any additional words.
Options:
[a] Cc1nc([N+](=O)[O-])c(N2CCN(C)CC2)n1Cc1ccccc1
[b] COCCCNC(=O)CN(Cc1ccc(Cl)cc1)S(C)(=O)=O
[c] COc1ccc(-c2cc(=O)c3cc(OC)ccc3[nH]2)cc1
[d] Cc1ccc(C2C3=C(CCCC3=O)N=C3c4ccccc4C(=O)C32)cc1
[e] COc1ccc(N2CCN(C(=S)Nc3cccc(C)c3)CC2)cc1
Answer: b. COCCCNC(=O)CN(Cc1ccc(Cl)cc1)S(C)(=O)=O
