Problem statement: Answer the multiple choice question.
Question: Which compound has a 5.396\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) Cc1ccc([N+](=O)[O-])c(NC(=O)COC(=O)C2CC3CCCC(C2)C3=O)c1C
(b) CC(=O)c1c(C(C)=O)c(C)n(-c2cccc3cccnc23)c1C
(c) O=c1cc(N2CCc3ccccc3C2)[nH]c(=O)n1-c1ccc(Br)cc1
(d) CN(C(=O)c1ccc(NC(=O)Cc2ccc(NC(=O)C3CCCN(C(=O)C4CCC4)C3)cc2)cc1)C1CC1
Answer: a. Cc1ccc([N+](=O)[O-])c(NC(=O)COC(=O)C2CC3CCCC(C2)C3=O)c1C
