Quizplus · Accepted Answer

The closure of the epiphyseal plate is prompted by the ossification of the zone of proliferation, which means that the cartilage cells stop dividing and start being replaced by bone tissue. This process usually happens between the ages of 18 and 21. Therefore, choice A is the most appropriate answer. Choices B, C, and D are incorrect because they do not relate directly to the closure of the epiphyseal plate.
