The answer is definitely A
Mainly Osteoarthritis (OA) happens when the joint-associated problems that can occur as normal changes to the articular cartilage as an individual ages.
It is a classic age-related disorder. It is often described as a chronic degenerative disease and thought by many to be an inevitable consequence of growing old. Cartilage is a firm, slippery tissue that enables nearly frictionless joint motion. Eventually, if the cartilage wears down completely, bone will rub on bone. In OA, degradation and loss of the articular cartilage is a central feature that is sometimes attributed to "wear and tear".
Beside Osteoarthritis, fibrillation of the articular surface, decrease in the size and aggregation of proteoglycan aggrecans, increased collagen cross-linking and loss of tensile strength and stiffness happens.

Answer:
Profase I
Explanation:
La Profase I es la primera etapa de la meiosis en la cual el material genético se condensa para formar los cromosomas y se desarrolla el huso acromático (huso meiótico). El entrecruzamiento, también conocido como sobrecruzamiento o <em>crossing-over</em> (por su nombre en inglés), es un proceso que consiste en el intercambio de material genético entre cromátidas no hermanas de cromosomas homólogos. El entrecruzamiento se produce durante la Profase I, es decir, durante el período inicial del primer ciclo celular meiótico (meiosis I). El sobrecruzamiento tiene una importancia fudamental desde el punta de vista evolutivo ya que este fenómeno incrementa la diversidad genética de las gametas obtenidas mediante este proceso.
