Which of the following muscular disorder is inherited ?

Options

A. Tetany
B. Muscular dystrophy
C. Myasthenia gravis
D. Botulism

Answer

To determine which muscular disorder is inherited, we will analyze the options provided and identify the one that is passed down genetically.

### Step-by-Step Solution:

1. **Identify the Disorders**: The question lists several muscular disorders. We need to identify each one:
- Titanic
- Muscular Dystrophy
- Myasthenia Gravis
- Botulism

2. **Analyze Titanic**: Titanic is associated with low blood calcium levels leading to fragile muscles and pain. It is not an inherited disorder; rather, it is a condition that arises due to nutritional deficiencies.

3. **Analyze Muscular Dystrophy**: Muscular Dystrophy is an X-linked recessive disorder. This means it is inherited from parents to offspring, specifically affecting males more severely. The condition leads to muscle weakness and degeneration. Therefore, this disorder is inherited.

4. **Analyze Myasthenia Gravis**: Myasthenia Gravis is a neuromuscular disorder characterized by weakness in skeletal muscles. It is not inherited but rather an autoimmune condition where the immune system attacks the connections between nerves and muscles.

5. **Analyze Botulism**: Botulism is caused by a bacterial infection from Clostridium botulinum. It is not an inherited disorder; it results from exposure to the bacteria, often through contaminated food.

6. **Conclusion**: After analyzing all the options, we conclude that Muscular Dystrophy is the only inherited muscular disorder among the ones listed.

### Final Answer:
The inherited muscular disorder is **Muscular Dystrophy**.
