The correct option is B X - sunlight, Y - glucose
All green plants perform photosynthesis. During this process, chlorophyll in plants utilise solar energy to convert carbon dioxide to glucose. Water is broken down in the process to release oxygen. Oxygen and glucose are used by plants during respiration. Energy is produced which is utilised to carry out all the processes in the cell.
So, in the process of photosynthesis, carbon dioxide, water, chlorophyll and sunlight is used while oxygen and glucose is produced.
