B. Infertility is defined as the inability to produce a viable offspring and is always due to defects/abnormalities in the female partner.
C. Infertility is due to immature sex organs.
D. Infertility cannot be helped by ART.

Answer

To determine the most appropriate statement of infertility, we can analyze the provided options step by step.

### Step-by-Step Solution:

1. **Understanding Infertility**:
- Infertility is defined as the inability to conceive after one year of unprotected sexual intercourse. This means that a couple is considered infertile if they cannot achieve pregnancy despite trying for a year without using any contraceptive methods.

2. **Evaluating the Statements**:
- **Option A**: "A couple is unable to produce children in spite of unprotected sexual cohabitation."
- This statement aligns with the definition of infertility, as it emphasizes the inability to conceive after a year of trying without protection.

- **Option B**: "Infertility is defined as the inability to produce a viable offspring and is always due to defects or abnormalities in the female partner."
- This statement is incorrect because infertility can be due to factors in either the male or female partner, and it does not always relate to the inability to produce viable offspring.

- **Option C**: "Infertility is due to immature sexual organs."
- This statement is misleading. While immature sexual organs can be a cause of infertility, it is not the only reason, and not all cases of infertility are due to this issue.

- **Option D**: "Infertility cannot be helped by ART."
- This statement is false. Assisted Reproductive Technology (ART) includes various medical procedures that can assist individuals or couples facing infertility issues.

3. **Conclusion**:
- After evaluating all the statements, **Option A** is the most appropriate statement of infertility, as it accurately reflects the definition and understanding of the condition.

### Final Answer:
The most appropriate statement of infertility is **Option A**: "A couple is unable to produce children in spite of unprotected sexual cohabitation."
