angle 2 = 103° ( vertically opposite angles )

angle 1 = angle 3

103° + 103° + 2 ( angle 1 ) = 360° ( angle 1 = angle 3 )

or, 206° + 2 (angle 1) = 360°

or, 2(angle 1) = 360 - 206

or, 2(angle 1) = 154°

or, angle 1 = 154/2 = 77°

Answer:

angle 2 = 103° (vertically opposite angles)

angle 1 = angle 3 = 77° (vertically opposite angles)

OPTION A IS CORRECT.
