Which one among the following statements is correct ?

Concave mirrors are widely used as reflectors in devices like torches, searchlights, and vehicle headlights to produce powerful parallel beams of light [c1][c2]. They are also utilized as shaving mirrors because they provide an enlarged, erect image when the object is placed close to the mirror [c2][t1]. In medical applications, dentists and doctors use concave mirrors to examine the oral cavity or teeth, as they provide a magnified view [c1][t3]. Conversely, convex mirrors always form virtual, erect, and diminished images, making them unsuitable for shaving or detailed medical examinations [c3][c4]. While convex mirrors are used as rear-view mirrors in vehicles to provide a wider field of view, they are not the standard choice for reflectors in torches or headlights where concentrated beams are required [c2][t9]. Therefore, the statement that concave mirrors are used as reflectors is the most accurate.
