Solution:

Concept- A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.
Quadrilateral features, particularly the angle sum property, will be used.

(n - 2) 180^{o}

is the formula for the angle sum of an n-sided polygon.
We are aware that a polygon with four sides is a quadrilateral. It might or might not be typical. Any angle with a value of 90 is a right angle. In order to get the number of right angles in a quadrilateral, we will first find the total number of angles and then divide that number by 90.
The total of a quadrilateral's angles,
=

(n - 2) 180^{o} = (4 - 2) 180^{o} = 360^{o}

The number of right angles in 360 degrees is
=

\frac{360}{90} = 4

Hence, the correct answer is option 3) 4.
