The product of two consecutive positive integers is divisible by

• A. $2$
• B. $3$
• C. $4$
• D. None of these

Answer 1

Answer: (A)

$2$

Let us consider two consecutive numbers, $2$ and $3$. or $21\&22$

$\therefore 2\times 3=6$ and .$21\times 22=462$

Since, $6and462$ are even numbers divisible by $2$.

So, option A is correct.
