Answer: B. [tex]3+(1+11)=15[/tex]


Step-by-step explanation:

1. By definition, the associative property of addition is:

[tex](a+b)+c=a+(b+c)[/tex]

2. Therefore, if you have the following expression:

[tex](3+1)+11=15[/tex]

You apply  the Asociative property of addition by regrouping the numbers as following:

[tex]3+(1+11)=15[/tex]

3. Then, you can conclude that the correct option is B.
