Answer:
The correct answer will be option-C.
Step-by-step explanation:
The bones and muscles in animal cells form the framework of the body or the skeletal system of the body.
The molecules which form the framework or act as the skeletal system of the cell are known as the cytoskeleton.
The cytoskeleton consists of three types of structures called microtubules, intermediate filaments and the micro-filaments. They all play an important role as they maintain the structural integrity of the cell as well as in the various process of the cell-like cell division.
Thus, Option-C is the correct answer.
