All options except Option D , a² + b² , is the square of the binomial.
<h3>What is a Binomial ?</h3>
A polynomial that contains only two term is called a Binomial.
The sum of square of a binomial is the sum of square of the first term , square of second term and twice of the product of the first and second term.
(a+b)² = a² +b² +2ab
(a-b)² = a² +b²-2ab
The options have to be broken down into this form to check whether they are square of a binomial
Option A : 4m² - 6mn + 9n² = (2m -3n)²
Option B: 16x² + 24xy + 9y²=(4x+3y)²
Option C : c²- 2cd - d²=(c-d)²
Option D : a² + b² cannot be written as the square of binomial.
All options except Option D is the square of the binomial.
