C. The M checkpoint, also called the spindle checkpoint or the mitotic checkpoint, makes sure that chromosomes are correctly attached to spindle fibres and that they are aligned at the metaphase plate during mitosis. DNA replication, which takes place during the S-phase of the cell cycle, is not regulated by it. Hence option C is correct.

A. The G1 checkpoint determines if the cell has sufficient nutrients, energy, and raw materials to begin DNA synthesis, hence option a. "adequate reserves" is a good fit. Hence option A is incorrect.

B. The G2 checkpoint determines whether the cell has finished DNA replication and has enough proteins to begin mitosis, hence option b. "G2 checkpoint-protein reserves" is a good match. Hence option B is incorrect.

D. Because cyclins are regulatory proteins that bind to and activate cyclin-dependent kinases (Cdks), which control the progression of the cell cycle, option d. Cyclins-Cdks is a suitable match. Hence option D is incorrect.
