Option B: Peas are the fruit of Pisum sativum. They are leguminous plants that help in nitrogen fixation in which the atmospheric nitrogen is fixed into nitrogen compounds that can be easily used by the plants.Therefore, this is the incorrect option.

Option C: Onion which is also known as bulb onion is a vegetable that is cultivated throughout the world. It belongs to the genus of Allium. Onions are the modified leaves of the plant that become fleshy as they store water, food materials and mucilage of the plants.Therefore, this is the correct option.

Option D: Bean is the seed of the flowering plant Fabaceae. These can be cooked in many ways. They are leguminous plants that help in nitrogen fixation in which the atmospheric nitrogen is fixed into nitrogen compounds that can be easily used by the plants.Therefore, this is the incorrect option.
