The pie chart presents the percentage contribution of different macronutrients to a typical 2,000 kcal diet of a person. The typical energy density (kcal/g) of these macronutrients is given in the table. The total fat (all three types), in grams, this person consumes is

To find the total fat consumed in grams:

1. Calculate the total percentage contribution of all fats:

   $$\text{Total fat \%} = \text{Unsaturated fat} + \text{Saturated fat} + \text{Trans fat}$$

   $$\text{Total fat \%} = 20\% + 20\% + 5\% = 45\%$$

2. Calculate the total energy obtained from fats in a 2,000 kcal diet:

   $$\text{Energy from fat} = 45\% \times 2000\text{ kcal} = 0.45 \times 2000 = 900\text{ kcal}$$

3. Convert energy into mass (grams): From the given table, all three types of fat have an energy density of $9\text{ kcal/g}$.

   $$\text{Total fat (grams)} = \frac{900\text{ kcal}}{9\text{ kcal/g}} = 100\text{ g}$$

Hence, the correct option is (C).
