The correct option is C Arachis hypogea
The peanut or groundnut (Arachis hypogaea) is a species in the family Fabaceae. The peanut was probably first domesticated and cultivated in the valleys of Paraguay. It is an annual herbaceous plant growing 30 to 50 cm tall. Peanut oil is often used in cooking, because it has a mild flavor and a relatively high smoke point. Due to its high monounsaturated content, it is considered healthier than saturated oils and is resistant to rancidity. There are several types of peanut oil including aromatic roasted peanut oil, refined peanut oil, extra virgin or cold pressed peanut oil and peanut extract. In the United States, refined peanut oil is exempt from allergen labeling laws.
Peanut oil is not obtained from Lathyrus odoratus (sweet pea), Pisum sativum (garden pea), Glycine max (soya) or Brassica juncea (mustard).
Therefore, the correct answer is option C.
