**Answer:**

**option (a) shows that the commutative property do not holds under subtraction.**

**(a) 5 – 1 ≠ 1 – 5 **

**Step-by-step explanation:**

Given : Some options showing operation subtraction.

We have to choose out of given options which one shows that the commutative property doesn't work under subtraction.

**Commutative property under addition states that for given any two positive numbers and b then following property holds ** that is it is irrespective of place the numbers are arranged like 2 + 3 = 3+ 2

but when we subtract two number the order or place of number matters.

Like 3 - 2 = 1 but 2 - 3 = -1 ≠ 1

**Thus, the commutative property do not holds under subtraction.**

** 5 – 1 = -4 ≠ 1 – 5 = -4 **

**So, option (a) shows that the commutative property do not holds under subtraction.**
