Answer : concave mirror

Answer 2

Spoon acts like option b: Concave mirror in this case.

• The type of image of objects formed on a mirror or lens depends on the distance between both of them.
• Stainless steel spoon has two sides where one side is curved as concave and another side is curved as convex type.
• The side where the curve is inwards is called the concave side and the other side is the convex side.
• A concave mirror forms an image of an object real or virtual and inverted or upright depending on its distance from the object.
• When an object is at a greater distance than the focal length of the mirror (concave), it forms a real and inverted image. That's why a person sees his face upside down because it is the concave side of a spoon.
• The convex mirror does not form inverted images.
• Both lenses are incorrect here because the side of the spoon does not behave as a lens.
• Therefore, the spoon acts as a concave mirror here.
