Myofibroblasts possess which components?

Explanation:
Myofibroblasts combine features of fibroblasts with smooth muscle–like contractility. They have actin and myosin filaments, allowing them to contract, and they also retain fibroblast characteristics that enable production of connective tissue components such as collagen. This combination lets them both pull wound edges together and synthesize extracellular matrix for healing. The other options don’t fit because keratin filaments are typical of epithelial cells, chondroitin sulfate is a cartilage-associated glycosaminoglycan, and elastin filaments provide elasticity in tissues rather than the contractile machinery seen in myofibroblasts.
