What condition is associated with Vitamin A deficiency?

Vitamin A deficiency is primarily associated with nyctalopia, which is commonly known as night blindness. This condition occurs because vitamin A is essential for the production of rhodopsin, a pigment in the retina that is crucial for low-light vision. When there is insufficient vitamin A in the body, it compromises the ability to see in dim light conditions, leading to difficulty seeing at night or in low-light environments.

Other options refer to different vitamin deficiencies or health conditions; for instance, anemia is generally linked to deficiencies in vitamins such as B12 or folate, scurvy is caused by a deficiency of vitamin C, and rickets is associated with a deficiency in vitamin D, calcium, or phosphate. Therefore, nyctalopia is the direct result of lack of adequate vitamin A, making it the correct answer in this context.
