Through which process is oxygen released into the atmosphere?
A
Combustion
B
condensation
C
photosynthesis
D
Nitrification
Explanation: 

Detailed explanation-1: -Photosynthesis is a process by which green plants prepare their own food from carbon dioxide and water in the presence of sunlight. During this process, oxygen is released.

Detailed explanation-2: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-3: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Detailed explanation-4: -photosynthesis is the process which releases oxygen.
