Which of the following steps is/are incorrect while constructing an angle of 120°?
Step 1 : Draw any line MN and take a point C on line.
Step 2 : Place the pointer of the compass at C and draw an arc of convenient radius which cuts the line at A.
Step 3 : Without disturbing the radius on the compass draw an arc with A as centre which cuts the first arc at B.
Step 4 : Again without disturbing the radius on the compass and with M as centre, draw an arc with O which cuts the first arc at C.
Step 5 : Join OA. ∠ OAN is the required angle of measure 120°.

A Only step 1
B Both step 4 and step 5
C Only step 5
D Only step 2
