Answer:

Option: d is the correct answer.

       d.   Square of a Binomial

Step-by-step explanation:

Binomial--

Binomial is a expression consisting of two terms.

( since bi basically means two)

Now here we have a identity as:

     [tex](3+6)^2=81[/tex]

i.e. there are two terms 3 and 6 which are separated by a addition sign and hence we square this binomial to get the desired value.

Since 6+3=9

and [tex](6+3)^2=9^2=81[/tex]

       Hence, the answer is:

            Square of a binomial.
