Answer : a
Hints & Solution
(a) Physiological value of carbohydrates is $4.0 kcal / g$, proteins $4.0 kcal / g$ and of fats is 9.0 $kcal / g$. Hence,
$5 g$ raw sugar will yield $5 \times 4.0=20.0 kcal$
$4 g$ albumin (protein) will yield $4 \times 4.0$
$=16.0 kcal$
$10+2 g$ of fat will yield $12 \times 9.0$
$=108.0 kcal$
Total yield $=144 kcal$.
