• B

  164
• C

  112
• Correct answer
  D

  144

Solution

For carbohydrates, calorific value $=$ 4 Thus, Raw sugar (carbohydrate) produce $=5 \times 4=20 \mathrm{kcal}$ Albumin (protcin) produce $=4 \times 4$ $=16 \mathrm{kcal}$ Ghee and vegetable oil (fat) $=9 \times$ $(10+2)=108 \mathrm{kcal}$ Total calories yield $=20+16+108$ $=144 \mathrm{kcal}$

Hence, the correct answer is option: 'D'.
