Hint:- In this question use this concept that the difference between two consecutive numbers is one and if one number is odd the other would be even.

__Complete step-by-step solution__ -

Let one number is taken as $x$

Since the difference between two consecutive numbers is one and if one number is odd the other would be even.

Therefore the difference between two consecutive even numbers or two consecutive odd numbers would be two.

Hence if one number we have taken is $ x $ the other would be either $ x - 2 $ or $ x + 2 $.

Therefore the correct option is B.

Note:- In this question we assumed the other number to be $x$ and as we concluded that the difference between two consecutive even numbers or two consecutive odd numbers would be two therefore the other number would be either $x - 2$ or $x + 2$.
