Explanation:

The correct answer is Section 2(b) of the Probation of Offenders Act, 1958. This section specifically defines the term 'Probation Officer' within the context of the Act. A Probation Officer plays a crucial role in the implementation of the Act, as they are responsible for supervising offenders released on probation, inquiring into the character and antecedents of offenders, and assisting the court in making appropriate orders. Their reports and recommendations are vital for the court to decide whether to release an offender on probation or to pass a sentence. The definition ensures clarity regarding the authority and functions of such an officer under the statute, distinguishing them from other legal or correctional personnel. Let's analyze the other options: Option (0) Section 2(a): This section defines the term 'Code'. Specifically, Section 2(a) states that 'Code' means the Code of Criminal Procedure, 1898 (now replaced by the 1973 Code). This definition is foundational for understanding the procedural framework within which the Probation of Offenders Act operates, but it does not define 'Probation Officer'. Option (2) Section 2(c): This section defines the term 'prescribed'. Section 2(c) states that 'prescribed' means prescribed by rules made under this Act. This definition is important for interpreting various provisions of the Act that refer to 'prescribed' procedures or conditions, indicating that such details are to be found in the rules formulated under the Act. However, it does not define 'Probation Officer'. Option (3) Section 2(d): This section defines the term 'supervision order'. Section 2(d) states that 'supervision order' means an order made under Section 4 directing that an offender shall remain under the supervision of a probation officer. This definition is critical for understanding the nature of probation and the role of the Probation Officer in ensuring compliance with such orders. While it relates to the Probation Officer's function, it is not the section that defines the term 'Probation Officer' itself.
