Which describes the role of oxygen in photosynthesis?

it is a reactant, so it is released by the plant.
it is a product, so it is released by the plant.
it is a reactant, so it enters the plant.
it is a product, so it enters the plant.

The oxygen gas is a product, so it is released by the plant.

Explanation:

Photosynthesis is defined as the process by which the producers make glucose with the help of carbon dioxide and water in the presence of sunlight.

The chemical equation representing this reaction follows:

In the above reaction, oxygen gas is written on the product side. So, it is formed by the plant and is released.

Hence, the oxygen gas is a product, so it is released by the plant.
