Given:
• The number x represents a positive integer
To find:
• Out of the given options, which one must be divisible by 3
Approach and Working:

o Considering the options given, option D shows 3 consecutive integers (x – 1), x, and (x + 1)
• If one of them is a multiple of 3, then their product is also a definite multiple of 3
Hence, the correct answer is option D.
