The best and most correct answer among the choices provided by your question is the third choice or letter C "commutative property of addition."
The word "commutative" comes from "commute" or "move around", so theCommutative PropertyΒ is the one that refers to moving stuff around. ForΒ addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2Γ3 = 3Γ2.

Answer:
Option C - Commutative property of addition
Step-by-step explanation:
Given : 7 + 9 + 3 = 7 + 3 + 9
To find : Which mathematical property is demonstrated?
Solution :
The given expression is 7 + 9 + 3
Now, we see there is an interchanging of position of 3 and 9.
which represent the commutative property.
There is addition in between the numbers.
So, the mathematical property used in expression is 'commutative property of addition'.
Therefore, option C is correct.
