Hint: Vision is an important sense which is usually obtained by the sense organs, eyes, and these organs are made up of different in various animals based on their necessity of vision, and it is very important for the organisms to move or travel safely, and to collect food, etc.

Complete answer:
Among all the living organisms on the earth, birds have more power of vision, and their vision is more powerful because of their adaptations such as to have a safe flight.
Eyes of the birds have various adaptations which have visual acuity which in general is superior than that of other vertebrates.
Acute vision is also one of the adaptation of the bird for their flight, as is mainly derived because of retina fovea, where this part has center which packed with 4 lakhs photoreceptors, even this number is higher than that of humans, where in the humans there are 2 lakhs photoreceptors, because of this birds have the sharpest vision.
The eyes of the birds are larger in size in proportional to that of head, where it is more than that of human head and eye proportion.
Eyes of birds have red, green, blue and ultraviolet cones which helps them to see the object even from very long distances where ultraviolet cones helps them to find the food in very long distance during their flight, where birds like hawks, vulture they can find small seeds, insects and fruits and whatever the food that they rely can be seen from the long distance and this is called as acute vision.

Hence, the correct option is A.

Note: Acute vision is seen in birds it helps them to have a great vision during flight, where they can identify their food from every height during flight, and these adaptations are mainly because of presence of more number of cones and at the same time, they have ultraviolet cones which provide very sharpest vision.
