Task: Answer the multiple-choice question.
Query: Which compound has a 2.952\% 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 other words.
Options:
a. CC(C(=O)OCC(=O)c1ccc(Br)cc1)N1C(=O)C2C3C=CC(C3)C2C1=O
b. CCOC(=O)C1=C(C)OC(N)=C(C#N)C1c1cccs1
c. Cc1ccc(OCCOC(=O)c2cc(S(=O)(=O)N3CCCCC3)ccc2N2CCOCC2)cc1
d. CC(C)CN(C(=O)COC(=O)c1ccc(Br)cc1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
Answer: a. CC(C(=O)OCC(=O)c1ccc(Br)cc1)N1C(=O)C2C3C=CC(C3)C2C1=O
