Skeletal muscle cells have multiple nuclei due to the fusion of myoblasts during development. This multinucleation is essential for muscle function and efficiency. The process contributes greatly to the growth and repair of muscle fibers. ;
The multiple nuclei in skeletal muscle cells result from the fusion of myoblasts during development. This process is essential for muscle growth and efficiency, allowing for effective regulation of metabolism and gene expression. Therefore, the correct answer is option a: fusion of myoblasts.
