To calculate the central angle for Party E, we use the formula:

$\text{Central Angle} = \left(\frac{\text{Percentage of Votes}}{100}\right) \times 360^\circ$

Given that Party E received 15.6% of the votes:

$\text{Central Angle} = \left(\frac{15.6}{100}\right) \times 360^\circ = 56.16^\circ$

The correct answer is 56.16°.
