The statement that asserts a true claim would be:
A). The height is approximately r units and the base length is approximately πr units.
The sector is described as an element of the circle or a part that extends to the center.
In the given figure, the height of the congruent sectors would be equivalent to r units as the radius is r units.
While the length of its base would be equivalent to πr units to denote the base length.
Thus, option A is the correct answer.
