Solution

The correct option is B
3,1,2

The steps for constructing $75^{\circ}$ angle is given below:

1. Draw an angle AOD = $90^{\circ}$ at a point O on the line segment OA.

2. At the point O, draw an angle AOE = $60^{\circ}$ .

3. Bisect the ∠DOE, so that ∠EOC = ∠DOC = $15^{\circ}$

$∠ A O C = ∠ A O E + ∠ E O C$ = $60^{\circ}$ + $15^{\circ}$ = $75^{\circ}$ .
