The answer is hard tissue.
Usually, hard tissue, such as bones and teeth or exoskeleton is much more preserved than soft tissue (organs, skin, etc.). Fossils become fossils by a process of mineralization. Hard tissues are more mineralized during life than organs. So it is no surprise that hard tissues take part in the process of mineralization and is preserved in fossils, unlike soft tissues.

Answer:
1) IRIS
2) LENS
3) RETINA
4) Fovea Centralis
Note: Answers 1 - 4 follows question pattern
Explanation:
The PUPIL is the hole in the MIDDLE of the IRIS of the eye, through which light passes to be focused on the RETINA.
The IRIS is the contractile membrane perforated by the pupil, which adjusts to control the amount of light reaching the retina, and which forms the colored portion of the eye
ACCOMMODATION is the change in the adjustment of the eye lens to help focus light ray.
RETINA helps to receive light rays that the lens has focused. It contains two cells: rods and cones
Fovea Centralis is at the center of the retina responsible for sharp and accurate vision, also it is where cones cells cluster.
I believe that it is D. All of the above.
