Answer

To solve the question regarding which autoimmune disorder involves the production of antibodies against acetylcholine receptors, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify an autoimmune disorder characterized by the production of antibodies against acetylcholine receptors.

2. **Review the Options**: The question likely provides several options. We need to analyze each one to determine if it fits the criteria.

3. **Analyze Each Option**:
- **Pernicious Anemia**: This disorder is primarily related to vitamin B12 deficiency and does not involve antibodies against acetylcholine receptors.
- **Hashimoto's Disease**: This is an autoimmune disorder affecting the thyroid gland, leading to inflammation and hypothyroidism, but it does not involve acetylcholine receptors.
- **Rheumatoid Arthritis**: This is an autoimmune condition that primarily affects the joints and does not target acetylcholine receptors.
- **Myasthenia Gravis**: This is a specific autoimmune disorder where the immune system produces antibodies against acetylcholine receptors, leading to muscle weakness.

4. **Identify the Correct Answer**: Based on the analysis, the disorder that fits the description of producing antibodies against acetylcholine receptors is **Myasthenia Gravis**.
