Arrange the sentence parts:
(A) the headmaster (B) for his punctuality (C) praised (D) the student

Correct option is D

Option (d) is the correct order of the given sentences.

· Prepositional phrase giving reason: (B) for his punctuality — “praise someone for something” is the correct collocation, so the reason naturally follows the object.
· Final sentence: “The headmaster praised the student for his punctuality.”
· Other orders break the standard S + V + O + (reason/modifier) flow or disrupt the fixed collocation praise … for ….
