Photorespiration is the light dependent process. At high temperature, RuBP carboxylase functions as oxygenase and instead of fixing carbon dioxide (C3 cycle), oxidises ribulose 1, 5-biphosphate to produce a 3-carbon phosphoglyceric acid and a 2-carbon phosphoglycolate.

Formation of 1 molecule of 3-C compound:
- RuBisCo enzyme in photorespiration catalyzes the oxygenation of RuBP (5-C compound) leading to the formation of one molecule of 3-PGA (3-C compound) and one molecule of 2-PGA (2-C compound).
- This process is known as the oxygenation activity of RuBisCo and occurs when the concentration of carbon dioxide is low and the concentration of oxygen is high, such as in hot and dry conditions.
- The 3-PGA molecule formed is then further metabolized in the Calvin cycle to regenerate RuBP and continue the process of carbon fixation.
Therefore, the oxygenation activity of RuBisCo in photorespiration leads to the formation of 1 molecule of 3-C compound (3-PGA) as a result of the oxygenation of RuBP.

Formation of 1 molecule of 3-C compound:
Photorespiration is a process that occurs in plants when the Calvin cycle is inhibited due to high temperatures or low carbon dioxide levels. During photorespiration, the enzyme RuBisCo, which is responsible for carbon fixation in the Calvin cycle, catalyzes a reaction that leads to the oxygenation of ribulose-1,5-bisphosphate (RuBP) instead of its carboxylation.
Resulting in the formation of 1 molecule of 3-C compound:
The oxygenation activity of RuBisCo in photorespiration leads to the formation of one molecule of 3-phosphoglycerate (3-PGA), which is a 3-carbon compound. This 3-C compound is then used in the subsequent steps of the photorespiratory pathway to eventually regenerate RuBP and continue the cycle.
Therefore, the correct answer to the question is option 'D', as the oxygenation activity of RuBisCo in photorespiration results in the formation of 1 molecule of a 3-C compound, specifically 3-phosphoglycerate.
