Answer 1

Answer: (A), (B), (D)

The correct options are

B Shaving and makeup mirrors
D Mirrors used in solar cooker

Concave mirrors are used in motor vehicle headlights to allow the light to spread to longer distances when the headlight bulb is placed at the its focus. Concave mirrors are used as shaving and makeup mirrors because objects held close are reflected in a concave mirror as a magnified image. Concave mirrors are used in solar cooker as they reflect sunlight in towards a single focal point. Rear side mirror of vehicles are convex as they capture a wider area of view.
