Answer: C

The key gives the order VI, I, III, IV, V, II for increasing sodium content per 100 g, which is meat, banana, tomato, spinach, musk melon and egg, with egg the richest source. Fruits and vegetables are generally low in sodium, while animal foods such as egg carry more. The question depends on the values in the food composition tables used by the setter, and the key follows that order, so option C is the answer. The other orders place egg or meat in different positions and do not match the key.
