An object is 100 mm in front of a concave mirror which produces an upright (erect image). The radius of curvature of the mirror is:(a) less than 100 mm (b) between 100 mm and 200 mm(c) exactly 200 mm (d) more than 200 mm

(d) More than 200 mm ​

Since the image formed is upright (erect image), the object lies within the focus of the concave mirror, because a concave mirror forms an erect image when an object is placed between the focus and the pole. This gives a radius of curvature greater than 200mm, as we know that radius of curvature is twice the focus (R = 2F).
