Answer 2

Main function of leaf is -

(c) Both 1 and 2

Explanation:

Leaves are appendages present in green plants.

They contain a pigment called chlorophyll which is necessary for photosynthesis. This photosynthetic reaction takes place in the leaves and results in the production of carbohydrates (food).

The lower surface of leaves has many small openings known as stomata. These pores help the  plant in the exchange of gasses with their surroundings.

Therefore it can be inferred that both the manufacture of food and exchange of gasses takes place through leaves.
