Final answer:
Seizures in infants during the 1950s were predominantly linked to a deficiency of Vitamin D, which is fundamental for proper bone development and the prevention of rickets. So, the correct answer is option 3.
Step-by-step explanation:
Seizures in infants in the 1950s were linked to a deficiency of Vitamin D. This vitamin is crucial for proper bone development and calcium absorption in the body. A deficiency in Vitamin D can lead to rickets, a condition that causes soft bones and skeletal deformities.
For a deeper understanding, rickets results from malabsorption of calcium and a deficiency in Vitamin D, and it is known that Vitamin D is stored in the body.
On reviewing various vitamins and their deficiencies, we see that Vitamin A deficiency typically results in issues with vision and immune function, while Vitamin E is necessary for reproductive health. To ensure an adequate intake of vitamins, a balanced diet is essential.
