• A. Ossification
• B. Mitosis
• C. Hypertrophy
• D. Atrophy

Answer: (C)

Verified step by step guidance

1. Understand the context of the question: The problem is asking about the biological process that leads to muscle enlargement due to exercise or weight lifting.
2. Clarify the term 'Hypertrophy': Hypertrophy refers to the increase in the size of muscle cells, which occurs when muscles are subjected to stress, such as during exercise or weight lifting. This is a physiological adaptation to increased workload.
3. Differentiate between the other terms: Ossification refers to the process of bone formation, not muscle enlargement. Mitosis is the process of cell division, which is not directly related to muscle growth in this context. Atrophy refers to the decrease in muscle size due to lack of use or disease, which is the opposite of hypertrophy.
4. Relate hypertrophy to exercise: During exercise, especially resistance training, muscle fibers experience micro-tears. The body repairs these tears, leading to an increase in muscle fiber size, which is hypertrophy.
5. Conclude the explanation: Based on the definitions and context, the correct term for muscle enlargement due to exercise or weight lifting is hypertrophy.
