Solution

The correct option is D $144^{\circ}$
$Required central angle = \frac{percentage of buyers}{100} \times 360^{\circ}$
$\frac{40}{100} \times 360^{\circ} = \frac{2}{5} \times 360^{\circ} = 144^{\circ}$
The central angle of the sector of the pie chart representing this information is $144^{\circ}$ .
