Answer:
The answer is A.
Explanation:
a+b=c+d
Given the expression,
11 + 7 = 5 + 13, where a= 11
b= 7
c= 5
d= 13
From the options, taking option A:
(5 + 6) + 7 = 5 + (6 + 7)
5 + 6= 11= a
7 = 7= b
5 = 5= c
6 + 7 = 13= d
Therefore from the comparison above, we can see that option A is the best form of expression that correctly interpretes the given expression
