The correct answer is option 4: Warburg effect.

The Warburg effect is the inhibition of photosynthesis in the presence of O2 in C3 plants. This phenomenon was first observed by Otto Warburg, who noticed that the rate of photosynthesis decreased significantly when O2 was present.

Option 1, Hexose monophosphate shunt, is not related to photosynthesis inhibition in C3 plants and is involved in carbohydrate metabolism.

Option 2, Pasteur effect, refers to the decrease in the rate of glucose consumption by cells in the presence of oxygen, but it is not specific to photosynthesis inhibition in C3 plants.

Option 3, Decker effect, is not a recognized term in the context of photosynthesis inhibition.

Therefore, the correct answer is option 4, Warburg effect.
