This question examines the understanding of the law of movement change.
Movement, change and development are both related and different;
(1) Contact:
① On the whole, the directionality is consistent: the three belong to the same sequence of concepts and categories in the scientific system of materialist dialectics, which all indicate that things are not absolutely static.
② The reason is the same: the interrelation and interaction between internal factors and things constitute the power and source of the movement, change and development of things, and promote the movement, change and development of things.
③ The scientific viewpoints expressed are the same: materialist dialectics is a science about the universal connection and eternal development of the world, and materialist dialectics combines movement, change and development to express its own development view.
(2) the difference:
① Different definitions: Motion refers to the changes and processes of everything in the universe; Change refers to the change of state and even nature of things in the process of movement, including quantitative change and qualitative change; Development refers to the emergence of new things and the demise of old things, that is, new things replace old things.
(2) Different emphases: Motion is the fundamental attribute and existing mode of matter, which mainly reflects the dynamic process of things' changes, indicating that things are in motion, contrary to the static view; Change mainly reflects the diversity, degree and state of the movement of things, indicating that things transition from one state to another, which is contrary to the view of solidification; Development focuses on the upward movement and change of things, reflecting the process of continuous replacement and generation of things from low to high and from simple to complex.
③ Different scope and depth: development is a kind of movement and change, but it cannot be said that movement and change are development. Movement and change are broader than development, while development is more profound than movement and change, which shows the general direction and trend of things' movement and change.
Judging from the above analysis, this question chooses a.
