The deficiency disease for vitamin B-12 is called pernicious anemia.

Explanation:

Vitamin B-12, also known as cobalamin, is essential for various bodily functions, including the formation of red blood cells and maintaining a healthy nervous system. Pernicious anemia develops when the body cannot absorb vitamin B-12 effectively, often due to a lack of intrinsic factor, a protein needed for vitamin B-12 absorption in the intestines. This condition can lead to various symptoms such as fatigue, weakness, and neurological issues, including numbness and cognitive disturbances. In contrast, the other options listed—spina bifida, pellagra, and beriberi—are associated with deficiencies of other vitamins, such as folate, niacin (vitamin B3), and thiamine (vitamin B1), respectively. It's critical to recognize the specific deficiencies associated with each nutrient to effectively address and treat them.
