Explanation:

The correct answer is Option (1): 'Section 7' of the Probation of Offenders Act, 1958. This section explicitly addresses the confidentiality of the Probation Officer's report. Section 7 states: 'The report of a probation officer referred to in sub-section (2) of section 4 or sub-section (2) of section 5 or sub-section (2) of section 6 shall be treated as confidential: Provided that the Court may, if it thinks fit, communicate the substance thereof to the offender and may give him an opportunity of producing such evidence as may be relevant to the matter stated in the report.' This provision ensures that the sensitive information gathered by a Probation Officer about an offender's character, antecedents, and social environment is protected, fostering trust and enabling the officer to obtain candid information. While the report is confidential, the proviso allows the court discretion to share its substance with the offender, ensuring fairness and the right to respond to adverse information. Let's analyze the other options: Option (0) 'Section 6': This section deals with 'Restrictions on imprisonment of offenders under twenty-one years of age'. It specifies that notwithstanding anything contained in any other law, when any person under twenty-one years of age is found guilty of having committed an offence punishable with imprisonment, the court shall not sentence him to imprisonment unless it is satisfied that, having regard to the circumstances of the case, including the nature of the offence and the character of the offender, it would not be desirable to deal with him under Section 3 or Section 4. This section focuses on the sentencing discretion for young offenders, not the confidentiality of reports. Option (2) 'Section 10': This section deals with 'Provisions as to sureties'. It clarifies that the provisions of Sections 122, 126, 126A, 406A, 514, 514A, 514B and 515 of the Code of Criminal Procedure, 1898, shall, so far as may be, apply in the case of bonds and sureties given under this Act. This section is concerned with the procedural aspects of bonds and sureties, not the confidentiality of the Probation Officer's report. Option (3) 'Section 9': This section deals with 'Procedure in case of offender failing to observe conditions of bond'. It outlines the steps a court can take if an offender released on probation fails to observe any of the conditions of their bond. This includes issuing a warrant, requiring the offender to appear, and potentially sentencing them for the original offense or imposing a penalty for the breach of conditions. This section is about enforcing the terms of probation, not about the confidentiality of reports.
