Hypermetropia and Blurred Vision
Hypermetropia, also known as farsightedness or long-sightedness, is a common refractive error of the eye. In hypermetropia, the eyeball is shorter than normal or the cornea is too flat, causing light rays to focus behind the retina instead of directly on it. This leads to difficulty in focusing on nearby objects, resulting in blurred vision.

Understanding the Question
The question asks which object someone with hypermetropia is most likely to see blurred. To determine this, we need to consider the characteristics of hypermetropia and how it affects vision at different distances.

Blurred Vision with Hypermetropia
In hypermetropia, the eye has difficulty in focusing on close objects. This is because light rays from nearby objects converge behind the retina instead of directly on it. Consequently, the image formed on the retina is blurred.

Analysis of the Options
a) Object 25cm away: This option is likely to be blurred because it is a close object, and individuals with hypermetropia have difficulty focusing on nearby objects.
b) Object 10m away: This option is at a medium distance and may not be as blurred as the object at 25cm away. However, individuals with severe hypermetropia may still experience some blurring.
c) Object 100m away: This option is at a far distance, and individuals with hypermetropia can usually see distant objects clearly. Therefore, this object is less likely to be blurred.
d) Object at infinity: The object at infinity refers to objects that are very far away, such as the horizon. People with hypermetropia can generally see distant objects clearly, so this object is unlikely to be blurred.

Conclusion
In conclusion, the object that a person with hypermetropia is most likely to see blurred is the object 25cm away. This is because hypermetropia primarily affects near vision, causing difficulty in focusing on close objects. The other options, which involve medium or far distances, are less likely to be blurred for individuals with hypermetropia.
