B. present from time of birth
C. mineral deficiency diseases
D. occur during life time

Answer

**Step-by-Step Solution:**

1. **Understanding Congenital Diseases**: Congenital diseases are conditions that are present at birth. They can be caused by genetic factors, environmental influences, or a combination of both.

2. **Identifying the Nature of Congenital Diseases**: These diseases are often inherited from parents to offspring, meaning they can be passed down through generations. This inheritance can occur through genes or chromosomal abnormalities.

3. **Examples of Congenital Diseases**: Some common examples of congenital diseases include hemophilia, color blindness, and Down syndrome. These conditions are typically due to genetic mutations or chromosomal abnormalities.

4. **Distinguishing from Other Diseases**: It is important to differentiate congenital diseases from other types of diseases, such as protein deficiency diseases or mineral deficiency diseases. The latter types usually develop during a person's lifetime and are not present at birth.

5. **Conclusion**: Therefore, congenital diseases are primarily genetic disorders that are present from the time of birth and can be passed from one generation to the next.

**Final Answer**: Congenital diseases are those which are present at birth and can be inherited from parents to offspring.
