At short focusing distances, ciliary muscles contract causing the suspensory ligaments to tighten.
The ciliary muscle is an integral muscle of the eye that is constructed as a ring of smooth muscle in the middle layer of the eye, the uvea (vascular layer). It regulates the passage of aqueous humor into Schlemm's canal and governs accommodation for observing objects at different distances.
A suspensory ligament is a ligament that provides support to a body part, particularly an organ. The suspensory ligament protects the fetlock from hyperextension (i.e., falling too low) during exercise. The ligament begins in both the fore and hindlimbs at its connection to the back of the upper cannon bone.
When the ciliary muscle relaxes, its diameter increases; when the suspensory ligaments tighten, the lens becomes thinner. This occurs when concentrating on a celestial object. When the ciliary muscle contracts, the lens becomes much more circular and has more focusing power because the pressure on the zonular fibers is reduced. When the ciliary muscles relax, these fibers contract, pulling the lens out and creating a flatter shape with less focusing power

Let us go over the definitions and the functions of each term:
a) Gene is a bit vague but in general it means a part of DNA that encodes one protein. Genes are the building blocks of our genomes but not the answer to this question.
b)mRNA. This is correct. The name itself means messengerRNA and its role is to copy the genetic information in the nucleus and bring it outside to be translated into protein.
c) ATP is an important molecule in our metabolism; energy is stored in this molecule and then used. It has no relationship to the mechanisms concerning DNA.
d) Thymine is one of the 4 nucleotide bases that are found in DNA, the other three being guanine, cytosine and adenine. They are essential components of a nucleotide (building blocks of DNA and RNA) but again, they do not transfer information out of the nucleus.
