Problem statement: Answer the multiple-choice question.
Query: Which compound has a 4.145\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) CCOC(=O)Cc1[nH]nc2c1C(c1cccc(OC)c1OC)C(C#N)=C(N)O2
(b) O=C(Nc1ccc(N2CCOCC2)cc1N1CCOCC1)c1ncoc1-c1cccc(F)c1
(c) Cc1[nH]n(-c2ccccc2)c(=O)c1C(C[N+](=O)[O-])c1ccc(F)cc1
Answer: a. CCOC(=O)Cc1[nH]nc2c1C(c1cccc(OC)c1OC)C(C#N)=C(N)O2
