The correct option is
C Groundnut
Peanut or groundnut (
Arachis hypogaea), is a species in the legume or "bean" family. The peanut was probably first domesticated and cultivated in the valleys of Paraguay. It is an annual herbaceous plant growing 30 to 50 cm (1.0 to 1.6 ft) tall. The leaves are opposite, pinnate with four leaflets (two opposite pairs; no terminal leaflet), each leaflet 1 to 7 cm ( to 2 in) long and 1 to 3 cm ( to 1 inch) broad.
Peanuts are known by many other local names such as earthnuts, groundnuts, goober peas, monkey nuts, pygmy nuts and pig nuts. Despite its name and appearance, the peanut is not a nut, but rather a legume.
India is the second largest producer of groundnuts in the world. Indian groundnuts are available in different varieties: bold or runner, Java or Spanish and red natal. The main groundnut varieties produced in India are Kadiri-2, Kadiri-3, BG-1, BG-2, Kuber , GAUG-1, GAUG-10, PG-1 , T-28, T-64, Chandra, Chitra, Kaushal, Parkash, Amber etc.
Thus, the correct answer is option C.
