Task: Answer the multiple choice question.
Question: Which compound has a 2.775\% 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) COc1ccc(OC)c(C(=O)NC(CC(N)=O)c2ccc(N3CCN(c4ccccc4)CC3)c([N+](=O)[O-])c2)c1
(b) Cc1ccc(-c2noc(C3CCCN(S(=O)(=O)c4ccc5ccccc5c4)C3)n2)o1
(c) COc1ccccc1/C=N/NC(=O)c1ccc2c(c1)OCO2
(d) Cc1ccc(-n2c(C)cc(C(=O)COC(=O)c3ccc[nH]c3=O)c2C)cc1
Answer: d. Cc1ccc(-n2c(C)cc(C(=O)COC(=O)c3ccc[nH]c3=O)c2C)cc1
