Solution
The correct option is B oxygen; carbon dioxide
Plant leaves and roots play a major role in the respiration process.
Leaves have tiny pores called stomata which helps in the gaseous exchange.
During respiration, the oxygen from the air enters the stomata and is utilised to produce energy, whereas carbon dioxide and water are given out as a waste product.
