Answer:
The correct answer is B
i.e. ∠DHB and ∠BHF are adjacent pair of angles
Step-by-step explanation:
Adjacent pair of angles are the angles that have a common vertex and a common side.
.In the given question H is the common vertex and HB is the common side.
So ∠DHB and ∠BHF are made with a common vertex H and side BH. So these are adjacent pair of angles.
