Options

B. Haemophilia
C. Cretinism
D. None of these

Answer

### Step-by-Step Text Solution:

1. **Definition of Hereditary Disease**: A hereditary disease is a condition that is passed down from parents to their offspring through genes. This means that the disease can be inherited and is often linked to genetic mutations or abnormalities.

2. **Evaluating the Options**:
- **Option 1: Diabetes**: While diabetes can have a genetic component, it is not strictly hereditary. It can also develop due to lifestyle factors, environmental influences, or other non-genetic reasons. Therefore, diabetes is not classified as a purely hereditary disease.

- **Option 2: Hemophilia**: Hemophilia is a genetic disorder that affects the blood's ability to clot properly. It is indeed a hereditary disease, as it is typically passed from parents to children through genes. Thus, this option is a hereditary disease.

- **Option 3: Cretinism**: Cretinism is primarily caused by a deficiency of iodine during pregnancy or early childhood, leading to developmental issues. It is not inherited genetically, so it is not considered a hereditary disease.

- **Option 4: Non-Hereditary Disease**: This option refers to diseases that do not have a genetic basis and are not passed from parents to children. This is a broad category that includes many conditions.

3. **Conclusion**: Based on the evaluation of the options, only hemophilia qualifies as a hereditary disease. The other options either have non-hereditary components or are entirely non-hereditary.

### Final Answer: Hemophilia is a hereditary disease.
