Explanation:

- Section 2(d) of the Probation of Offenders Ordinance, 1960 specifically provides the definition of a "Probation Officer."

- Option 1: Jail Officer

Not defined under this section. Jail officers are responsible for managing prisoners in jail, unrelated to the definition here.

- Option 2: Police Officer

This does not fit Section 2(d), as police officers enforce the law, not supervise probationers.

- Option 3: Probation Officer

Correct Answer. Section 2(d) defines a "Probation Officer," who supervises offenders released on probation by the courts.

- Option 4: None of above

This is incorrect, as one option fits the definition exactly.
