Correct option is B

Explanation of Sentence Order:
C (he constantly complains) – Subject + verb; this is the natural opening.
A (about all his) – Begins the object of complaint.
D (neighbours and the) – Completes the object of the preposition "about".
B (noise they make) – Further qualifies what the neighbours do; adds detail to the complaint.

So, the correct sequence is: C → A → D → B
