Answer: C. the fluid located in the main chamber of her eyeball.
Explanation:
A large part of the eye’s interior is filled with vitreous which is a gel-like substance/fluid that helps the eye maintain its round shape. Millions of fine fibers are intertwined within the vitreous that are attached to the surface of the retina which is the eye’s light-sensitive tissue. The vitreous shrinks slowly as one grow older, and these fine fibers looses on the retinal surface. Often times the fibers break, resulting in the vitreous to shrinking and separating from the retina which is known as Vitreous detachment.
When vitreous shrinks, it becomes like a string and the strands can put tiny shadows on the retina that you might notice as floaters which in appearance is as little “cobwebs” that tend to float about in your field of vision.
