The correct answer is option 'A' - 1985.

Explanation:
The Administrative Tribunals Act was passed by the Parliament of India in 1985. This act aimed to provide for the establishment of administrative tribunals for the speedy and effective disposal of disputes and complaints related to recruitment and conditions of service of persons appointed to public services and posts in connection with the affairs of the Union or any State.

Key Points:
1. Purpose of the Act: The Administrative Tribunals Act was enacted to address the growing number of cases related to service matters pending in regular courts. It aimed to provide a separate mechanism for the resolution of such disputes, ensuring a faster and more efficient process.

2. Establishment of Administrative Tribunals: The Act provided for the establishment of administrative tribunals at both the central and state levels. These tribunals were given the authority to adjudicate matters related to recruitment, conditions of service, and other administrative issues concerning public servants.

3. Composition of Tribunals: The Act specified the composition of the administrative tribunals. Each tribunal would consist of a Chairman and such number of Vice-Chairmen and Members as the government deemed necessary. The Chairman and members were appointed by the President or the Governor, as the case may be.

4. Jurisdiction of Tribunals: The administrative tribunals established under this act had the jurisdiction to hear and determine disputes and complaints arising out of service matters of public servants. They had the power to make orders and pass judgments, which were enforceable as if they were decrees of a civil court.

5. Exclusion of Jurisdiction of Civil Courts: One of the significant provisions of the act was the exclusion of the jurisdiction of civil courts in matters falling within the jurisdiction of administrative tribunals. This meant that once a dispute was referred to the tribunal, the civil courts could no longer entertain or decide upon the same matter.

6. Appellate Authority: The Act also provided for the establishment of a Central Administrative Tribunal (CAT) at the central level and State Administrative Tribunals (SATs) at the state level. The CAT and SATs served as appellate authorities, hearing appeals against the decisions of the administrative tribunals.

In conclusion, the Administrative Tribunals Act was passed by the Parliament of India in 1985 to establish administrative tribunals for the speedy and effective resolution of service-related disputes of public servants. This act aimed to streamline the process and ensure timely justice for the aggrieved parties.
