The given question is related to optics and the formation of images by a convex lens. Let's analyze the given information step by step.
Convex Lens:
A convex lens is a lens curved outward on both sides. It is thicker at the center and thinner at the edges. Convex lenses are also called converging lenses because they converge the incident light rays.
Virtual Image:
A virtual image is formed when the light rays appear to come from a point behind the lens. It cannot be obtained on a screen and is always erect (upright).
Erect Image:
An erect image is an image that is not inverted. It appears in the same orientation as the object.
Magnified Image:
A magnified image is an image that appears larger than the object. It can be larger in size or just appear closer.
Focal Length:
The focal length of a lens is the distance between the lens and the point where parallel light rays converge or appear to diverge from. For a convex lens, the focal length is positive.
Given Information:
The focal length of the convex lens is 10 cm.
Analysis:
Since the image formed is virtual, erect, and magnified, it means that the object is placed between the lens and its focus.
When an object is placed between the lens and its focus, a magnified and erect virtual image is formed on the same side of the lens as the object.
Therefore, the distance of the object from the lens is less than the focal length.
Solution:
The distance of the object from the lens is 5 cm. (Option B)
To summarize, when a virtual, erect, and magnified image is formed by a convex lens of focal length 10 cm, the object distance from the lens is 5 cm.

The distance of the object from the lens is 5 cm. (Option B)

For a virtual, erect and magnified image, object lie between F and C.
If F = 10 cm, r = F/2 = 5 cm which is OC.
If F = 10 cm, r = F/2 = 5 cm which is OC.
