We start by listing the given energy values per gram: Protein 17 kJ/g, Carbohydrate 17 kJ/g, Fat 37 kJ/g. Peter’s intake is 95 g protein, 135 g carbohydrate, and 65 g fat.

Compute energy from each macronutrient:
- Protein: 95 g × 17 kJ/g = 1615 kJ
- Carbohydrate: 135 g × 17 kJ/g = 2295 kJ
- Fat: 65 g × 37 kJ/g = 2405 kJ

Total energy intake is the sum of these three contributions: 1615 + 2295 + 2405 = 6315 kJ.

Now evaluate the first dropdown options for total energy intake. The options presented are 6315, 5015, 8215, and 6915. Since 6315 kJ matches the calculated total, the other numbers (5015, 8215, 6915) do not reflect the correct sum of the macronutrient energies provided.

Next, determine the protein contribution as a percentage of total energy intake. Protein energy is 1615 kJ, and the total energy is 6315 kJ. The fraction is 1615 / 6315 ≈ 0.256, which is about 25.6%. Rounding to the nearest whole percent gives 26%.

Review the second dropdown options for protein energy percentage: 32, 26, 51, and 43. Among these, 26% is the closest rounded value to 25.6%, while 32, 51, and 43 would misrepresent the proportion of energy from protein.

In summary:
- For total energy intake, the viable choice is 6315 kJ, while the others are not supported by the calculations.
- For protein energy percentage, the viable choice is 26%, since 1615 kJ out of 6315 kJ equals about 25.6%, rounding to 26%.
