Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.278% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) CC(C)C(NC(=O)CNC(=O)OC(C)(C)C)C(=O)NCc1ccccc1
(b) O=C(N/N=C/c1cccc([N+](=O)[O-])c1)c1c[nH]c2ccccc12
(c) COCc1ccc(CN2CCc3c([nH]c4ccccc34)C2CC(C)C)o1
(d) C=CCOC(=O)C1=C(C)NC(SCC(=O)Nc2ccccc2)=C(C#N)C1c1ccco1
(e) CCOC(=O)CCCNC(=O)COC(=O)c1cc(C)cc(C)c1
Answer: b. O=C(N/N=C/c1cccc([N+](=O)[O-])c1)c1c[nH]c2ccccc12
