I'd say your answer is,
C. the attraction and bonding of ions with equal opposite charges.
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

Pancreatitis is an inflammation of the pancreas that may be caused by years of heavy consumption of alcohol of gall stones. The pancreas plays major important roles such as secreting digestive juices into the small intestines, which help to digest fats, proteins, and the carbohydrates in food. It also release hormones insulin and glucagon that regulate the blood sugar. Pancreatitis is characterized by a pancreas being inflamed, therefore when this happens the body's normal complex coordination is disrupted and the enzymes in the pancreas are prematurely activated before they exit the organ, which results in these enzymes digesting the pancreatic tissue.
Conjugation. I hope this helps!
