Solution
The correct option is A The near point of his eyes has receded away
The student sitting on the last bench can read the letters written on the blackboard but is not able to read the letters written in his text book because he is suffering from hypermetropia or far sightedness. He can see distant objects clearly but cannot see nearby objects distinctly. This means that the near point of the eye is shifted from 25 cm to some other value greater than that. Thus the near point of the eye has receded away.
