Understand the definition of a sector of a circle: it is the region bounded by two radii and the arc between them.
Recall that a radius is a line segment from the center of the circle to any point on the circle.
Recognize that the two boundaries of the sector are these two radii, which form the 'sides' of the sector.
Note that the arc connecting the endpoints of these radii forms the curved boundary of the sector.
Conclude that the correct elements bounding a sector are the radii and the intercepted arc, not chords, diameters, or tangents.
