The correct option is
A Anabolic reaction
The anabolic processes are the reactions in which the smaller organic molecules are used for the production of the large complex molecules. Gluconeogenesis is the process which is used for the formation of glucose from the simpler substances. The formation of glucose mainly takes from non-carbohydrate carbon substrates such as lactate, glycerol, and glucogenic amino acids.
Thus, the correct answer is option A.
