The correct answer is (a). A person with myopia can see nearby objects clearly, but distant objects appear blurry. This is because the light rays from distant objects are focused in front of the retina, instead of directly on it. This can be corrected with glasses or contact lenses that have concave lenses, which bend the light rays so that they focus on the retina.
Option (b) is incorrect because a person with myopia cannot see distant objects clearly. Option (c) is incorrect because a person with myopia can only see nearby objects clearly, not distant objects. Option (d) is incorrect because a person with myopia can see nearby objects clearly, but not distant objects.
