Answer:

Option D is correct.

The length of AB = [tex]\sqrt{13}[/tex] units.

Explanation:

Use Distance(D) formula for two points (x_1 ,y_1) and (x_2 ,y_2) is given by:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

From the given figure in triangle ABC, A =(4,5) and B= (2,2),

then by using distance formula, we have;

AB =[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

AB=[tex]\sqrt{(2-4)^2+(2-5)^2}[/tex] or

AB=[tex]\sqrt{(-2)^2+(-3)^2}[/tex]

or

AB=[tex]\sqrt{(4+9}[/tex] = [tex]\sqrt{13}[/tex]

Therefore, the length of AB = [tex]\sqrt{13}[/tex] unit.
