The correct answer to this question is option 4, none of the above.

Let`s dissect each option to understand why they are not the correct answer.

Option 1: Myopia, also known as nearsightedness, is a condition where a person can see objects clearly up close but not at a distance. In this case, the person can see the object clearly when it is placed 25 cm away, which is considered up close. Therefore, myopia is not the correct answer.

Option 2: Hypermyopia is not a recognized medical condition. It seems to be a combination of hyperopia (farsightedness) and myopia (nearsightedness). Since it is not a recognized condition, it is not the correct answer.

Option 3: Astigmatism is a condition where the cornea or lens of the eye is not perfectly curved, causing blurred or distorted vision at any distance. Since the person in question can see the object clearly at a specific distance (25 cm), it is unlikely to be astigmatism.

Therefore, the correct answer is option 4, none of the above. However, if additional information or context is provided, the correct answer may change accordingly.
