<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 55-year-old male presents with left hip pain and stiffness. Radiographs are shown in Figures A and B. Serum alkaline phosphatase levels are elevated. A biopsy of the left femur is performed and shown in Figure C. Which of the following cells are initially responsible for this condition?? A: Osteoblasts, B: Osteoclasts, C: Neutrophils, D: T-Cells, E: Fibroblasts,  <response>: This is a question about a medical condition affecting the bone. The patient is a 55 year old male with left hip pain, stiffness, and elevated alkaline phosphatase levels. Radiographs show a lytic lesion in the left proximal femur. The biopsy shows sheets of plasma cells infiltrating the bone marrow. This presentation is most consistent with multiple myeloma, a plasma cell neoplasm that can cause lytic bone lesions. The key cells responsible for the lytic lesions are osteoclasts. Myeloma cells stimulate increased osteoclast activity leading to excessive bone resorption and destruction.Of the choices given, osteoclasts are the cells initially responsible for the lytic lesions and bone destruction in multiple myeloma.B: Osteoclasts
