Closure property of integers is valid for both addition and subtraction but commutative property of integers is invalid in the case of

The correct option is B subtraction
Commutative property of integers states that
a + b = b + a in case of addition.
But in case of subtraction, commutative property of integers is invalid, as
a - b $\ne$ b - a
Example : Let a = 3 and b = 5
a - b = 3 - 5 = -2
b - a = 5 - 3 = 2
$\therefore$ -2 $\ne$ 2
Hence, in case of subtraction of integers commutative property is invalid.
