Problem

Photosynthesis is a redox reaction i.e., XCO2+XH2O→Chlorophyllhv(CH2O)n+XO2\text{XCO}_2 + \text{XH}_2\text{O} \xrightarrow[\text{Chlorophyll}]{\text{hv}} (\text{CH}_2\text{O})_n + \text{XO}_2 ; which one is not correct about it: a. carbon is reduced and oxygen is oxidised b. it may be classified as intermolecular redox reaction c. O2\text{O}_2 released comes from H2O\text{H}_2\text{O} d. equivalent mass of CO2\text{CO}_2 is 11 and of H2O\text{H}_2\text{O} is 4.5
Intuitive explanation

Photosynthesis is fundamentally about tracking which atoms gain and lose electrons. The key is to assign oxidation states to carbon and oxygen in the reactants and products, then trace where the O2\text{O}_2 actually comes from using isotope labeling evidence. This lets you evaluate each claim about electron transfer and equivalent masses systematically.
