Detailed Solution & Explanation

The component costs are: - Raw Materials = 12\displaystyle 12 units - Labour = 20\displaystyle 20 units - Direct Production = 35\displaystyle 35 units - Others = 23\displaystyle 23 units Total components sum = 12+20+35+23=90\displaystyle 12 + 20 + 35 + 23 = 90 units. Since the total central angle in a pie chart is 360\displaystyle 360^\circ, each unit corresponds to: 36090=4\frac{360^\circ}{90} = 4^\circ The largest component is Direct Production (35\displaystyle 35 units) and the smallest component is Raw Materials (12\displaystyle 12 units). The difference in units = 3512=23\displaystyle 35 - 12 = 23 units. The difference between their central angles is: Difference=23×4=92\text{Difference} = 23 \times 4^\circ = 92^\circ This corresponds to Option D. Hence, **Option D** is the correct answer.
