Photorespiration involved the following reaction which occurs in the sequence of:

Explanation

Photorespiration is a process in plants where RuBP (Ribulose Bisphosphate) reacts with oxygen, rather than carbon dioxide, leading to a series of reactions:1. RuBP + O2 --> Glycolate: RuBP oxygenation is the first step, producing glycolate.2. Glycolate --> Glycine: Glycolate is then converted to glycine.3. Glycine --> Serine + CO2: Finally, glycine is converted to serine with the release of CO2.Option C correctly follows this sequence. Options A, B, and D misrepresent the order of these reactions, either starting with or incorrectly placing the reactions, which makes them incorrect.
