Solution.

Let us look at the meaning of each rule

Commutative property of addition: says changing the order of addends does not change the sum. For example, 4 + 2 = 2 + 4

Associative property of addition says changing the grouping of addends does not change the sum. For example, ( 2 + 3 ) + 4 = 2 + ( 3 + 4 )

While

Identity property of addition says that the sum of 0 and any number is that number. Here's an example: 0 + 4 = 4

0 + 4 = 4

Given 7 + [5+ (6)] = 7 + [(6) +5], we can see that the grouping of addends was chaneged and yet the sum does not change, hence this illustrate Associative property of addition

The coorect option is B. Associative property of addition
