Question

Which vitamin deficiency causes Lordosis in fish fry?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin E
• D. Vitamin D

Hint:

Lordosis = check Vitamin C in feed.

Answer 1

The Correct Option is B

Step 1: Vitamin C is essential for collagen synthesis and bone development.
Step 2: Deficiency leads to skeletal deformities like Lordosis (spinal curvature) and scoliosis in fish fry.
Step 3: Vitamin A relates to vision, D to bone mineralization but not curvature in fry, E to fertility and antioxidants.

Answer 2

Function-to-Deficiency Link: Trace the deficiency back to the vitamin's core biological job.

Vitamin C is essential for collagen synthesis, which builds cartilage and bone structure — without it, fish fry develop skeletal deformities like Lordosis (spinal curvature).

Vitamin A supports vision, Vitamin D supports bone mineralization (but not curvature specifically), and Vitamin E supports fertility/antioxidant defense — none of these ties directly to collagen-related spinal deformity.
