Answer:
A. Beef uses significantly more land than plants to produce 100 grams of protein
Explanation:
Let's examine each answer choice.
A. Beef uses significantly more land than plants to produce 100 grams of protein
This is true. Beef uses 163.6 square meters of land, while peas only use 3.4 square meters.
B. Meat production is more efficient than farming protein from fish and prawns
This is not true. Meat production is less efficient, because it uses more land than fish and prawns.
C. Lamb and mutton produce more protein per square meters than pig meat and poultry
This is false. Lamb produces less protein per square meter, because it takes 184.8 square meters to produce 100 grams of protein, while pig meat only takes 10.7 square meters to make the same amount.
D. Nuts and grains produce less protein per square meter than milk and cheese
This is false. Milk and cheese require more square meters per 100 grams of protein/ Therefore they produce less protein per square meter, not the nuts and grains.
So, the best answer choice is A. Beef uses significantly more land than plants to produce 100 grams of protein
