she answered \osteoblasts\.
the correct answer is:

Explanation:

Osteoblasts are responsible for bone formation by producing new bone matrix and replacing new bone cells. Wait, but the original answer marked a) as wrong? Wait, no, actually, osteoblasts are the cells that form new bone tissue (secrete osteoid which mineralizes into bone). Osteocytes are mature bone cells in lacunae, osteoclasts break down bone, and blood cells are for blood. So the correct answer should be a) Osteoblasts, but the image has a cross on a). Wait, maybe a typo? But based on bone cell functions: osteoblasts build new bone. So the correct answer is a) Osteoblasts.

Answer:

a) Osteoblasts
