The correct option is C Groundnut
Peanuts are rich in essential nutrients. In a 100 g serving, peanuts provide 570 calories and are an excellent source of several B vitamins, vitamin E, several dietary minerals, such as manganese (95% DV), magnesium (52% DV) and phosphorus (48% DV), and dietary fibre. They also contain about 52% protein per 100 g serving, a higher proportion than in many tree nuts. It has the highest amount of protein among the four. Thus, the correct answer is option C.
