The statement provided says that "The doctor is of the opinion that the patient’s condition would become normal after this operation." From this, we can infer the following:
- Conclusion I: The patient’s condition is such that he can be operated upon.
This conclusion follows from the statement. The doctor is suggesting that an operation is necessary to restore the patient’s condition to normal, which implicitly means the patient’s condition is operable. Thus, Conclusion I is valid.
- Conclusion II: Certain costly medicines can be administered to the patient and the operation may not be necessary.
This conclusion does not follow from the statement. The doctor specifically believes that the patient's condition will improve after the operation, without suggesting that expensive medicines could eliminate the need for surgery. Therefore, Conclusion II is not supported by the statement.
Since only Conclusion I is valid, the correct answer is (1).
