Question

what is the result of planting of large numbers of trees?
production of carbon dioxide will increase
production of carbon dioxide will decrease
production of oxygen will increase
production of oxygen will decrease

Explanation:

Trees perform photosynthesis, which uses carbon dioxide and produces oxygen. Planting more trees means more photosynthesis, so oxygen production increases. Carbon dioxide production (from tree respiration) isn't the main effect here, and more trees would actually help absorb CO₂, not increase its production. So the correct option is about oxygen production increasing.

Answer:

C. Production of oxygen will increase
