Tetany is caused by deficiency of:

• A. \(\text{Zinc}\)
• B. \(\text{Selenium}\)
• C. \(\text{Copper}\)
• D. \(\text{Calcium}\)

Hint:

Tetany is associated with low calcium levels (hypocalcemia), leading to muscle spasms and nervous system disturbances.

Answer 1

The Correct Option is D

Step 1: Understanding tetany.
- Tetany is characterized by involuntary muscle contractions or spasms, which result from a deficiency of ionized calcium in the blood.
Step 2: Explanation of incorrect options.
- Zinc (A), Selenium (B), and Copper (C) are crucial for various metabolic processes, but they do not directly cause tetany.
Step 3: Selecting the correct option.
- Since calcium deficiency leads to tetany, the correct answer is (D) Calcium.
