Look carefully at the statement given:

3 + (5 + 4) = (5 + 4) + 3

Look at Left-hand side:

a = 3 and b =(5 + 4)

Now, look at Right-hand side:

b = (5 + 4) and a = 3. Therefore:

a + b = b + a sub the values of a and b above into this equation:

3 + (5 + 4) = (5 + 4) + 3

And that is why G is the answer. Got it?.
