The given statements tell us that lawyers marry only fair girls, and Shobha is very fair. However, it does not specify whether Shobha is married or not, nor does it state that she is married to a lawyer. Therefore:
- Conclusion I: ``Shobha is married to a lawyer" is not necessarily true. Shobha is fair, but the statement does not guarantee that she is married to a lawyer.
- Conclusion II: ``Shobha is not married to a lawyer" is also not necessarily true. The statement does not provide enough information to conclude that Shobha is not married to a lawyer.
Since both conclusions are possibilities based on the given information, the correct answer is Option D (Either conclusion I or II follows).
