The given angles sum to less than 90°, so the remaining angle must be more than 90°. (The total of all angles is 180°.) Triangle ABC has an angle greater than 90°, so is obtuse. Since the triangles are similar, their corresponding angles are congruent. Hence ...
.. D. Triangle XYZ is obtuse.
Images are focused by the lens onto the retina which is a face at the back of the eye upon which light sensitive cells (rods and cones) convert the incident light into electrical signals that are transmitted to the brain.
The fovea is a pit directly behind the lens on the retina that contains a concentration of light sensitive, closely packed cones (colour sensitive cells) and is responsible for sharp central vision.
