see the attached figure to better understand the problem

In the figure

Angle A and Angle B are vertical angles

so

∠A=∠B

Angle C and Angle D are vertical angles

so

∠C=∠D

Angle A and Angle C are supplementary angles

so

∠A+∠C=\(180\°\)

Angle D and Angle B are supplementary angles

so

∠D+∠B=\(180\°\)

therefore

∠A+∠C+∠D+∠B=\(360\°\)

the answer is the option C

\(360\°\)
