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.
