The correct answer is
Vitamin A
A deficiency of Vitamin A can lead to night blindness, as this vitamin is essential for the production of rhodopsin, the pigment needed for low-light vision.
Vitamin B12, D and C deficiencies are linked to other health conditions, not night blindness specifically.
Hence, Vitamin A is the correct answer.
