Explanation:

- Section 18 of the Probation of Offenders Act, 1960 specifically deals with the making of rules by the State Government to carry out the objectives of the Act.

- Option 1: Making of rules – This refers to empowering the government to lay down detailed procedures and rules. This is what Section 18 covers.

- Option 2: Making of Probation Centres – There is no specific section in the Act dedicated solely to establishing probation centres.

- Option 3: Promotions of Probation Officers – The Act does not contain a section about promotions. Such service matters are usually handled by government service rules, not the Act.

- Option 4: None of above – Incorrect, as option 1 is correct.

- Section 18 ensures there is flexibility for implementing the Act through rules.
