The question is asking about the proportions of carbohydrate and protein in a balanced diet for an adult working man.

Option 1, the correct answer, states that 600 grams of carbohydrate and 420 grams of protein should be consumed. This is in line with general nutritional advice, which typically recommends a higher intake of carbohydrates than protein for energy, fibre, and to fuel physical activity.

Option 2 suggests an equal intake of carbohydrates and protein (600 grams each), but as stated, carbohydrates are needed in greater amounts for their energy contribution.

Option 3 suggests more protein (600 grams) than carbohydrates (420 grams). This is not typically suggested for a balanced diet as excessive protein can lead to kidney damage while insufficient carbohydrates can reduce energy levels.

Option 4 proposes an equal intake of 420 grams of carbohydrates and protein, which also doesn`t follow the generally advised proportion in a balanced diet.

However, remember that individual diet requirements can vary greatly depending on a person`s activity levels, age, health status and other factors, so these numbers are general averages and may not be appropriate for everyone.
