{'corrective glasses': [0, 0, 1, 0], 'distant objects': [0, 0, 1, 3], 'nearby objects': [0, 0, 1, 0], 'myopia': [2, 0, 0, 3], 'hypermetropia': [0, 0, 0, 1], 'presbyopia': [0, 0, 0, 1]}

The correct answer is Option 1: 1, 2 and 3.

Let`s analyze each statement to understand why it is incorrect:

Statement 1: A person with myopia can see distant objects distinctly but cannot see nearby objects clearly.

This statement is correct. Myopia, or nearsightedness, is a condition where a person can see nearby objects clearly but has difficulty seeing distant objects.

Statement 2: A person with hypermetropia cannot see distant objects clearly.

This statement is incorrect. Hypermetropia, or farsightedness, is a condition where a person can see distant objects clearly but has difficulty focusing on nearby objects.

Statement 3: A person with presbyopia can see nearby objects without corrective glasses.

This statement is incorrect. Presbyopia is an age-related condition where a person loses the ability to focus on nearby objects, and reading glasses or corrective lenses are required to see nearby objects clearly.

Since all three statements provided are incorrect, the correct answer is Option 1: 1, 2 and 3.
