Answer 1

Answer: (A), (B), (C)

The correct options are
A Addition
B Subtraction

Take $2$ integers $3$ and $5$

$3+5=8$. $8$ is an integer.

$3\times 5=15$. $15$ is an integer.

$3-5=-2$ .$-2$ is an integer.

$3÷5=\frac{3}{5}$. $\frac{3}{5}$ is not an integer.

Integers are closed under addition, subtraction and multiplication.

So, options A, B and C are correct.
