B Correct answer
Explanation

Cellular respiration occurs in all living cells (plant and animal) as it's essential for energy production. In plants, respiration happens continuously, day and night, in mitochondria. While plants produce oxygen during photosynthesis (which only occurs in light), they simultaneously consume oxygen for respiration. Respiration never produces vitamins.
