Final answer:
The query is related to the biology of the human eye, asking to calculate the image height of a 3-meter tall tree on the retina from 25 meters away. Through proportions, the image height is found to be 0.24 cm. Therefore the correct option is A.
Step-by-step explanation:
The question pertains to a high school level biology topic about the height of a tree. Specifically, the problem asks for the calculation of the image size on the retina when viewing a tree that is 3 meters tall from a distance of 25 meters. Using the physics of the human eye, one can calculate the image size using a proportion based on similar triangles formed by the distance of the object (the tree), its actual size, and the cornea-to-retina distance within the eye. Assuming that the eye creates similar triangles, the ratio of the tree's height to its distance from the observer (3/25) should be equal to the ratio of the image's height on the retina to the cornea-to-retina distance (x/2 cm). Solving for x gives us 0.24 cm, which matches option A.
