Who among the following Governors of Haryana was a civil servant?

A career civil servant is a government official who reaches senior administrative posts through a service examination and postings inside the government machinery (for example, the Indian Administrative Service, IAS) — distinct from a politician, who reaches high office through elections, party organisation, and legislative or ministerial roles. Judging which named Governor "was a civil servant" means checking each person's pre-gubernatorial career against this administrative-service-versus-elected-politics test.

Checking each of the four names against that test:

• Muzaffar Hussain Burney joined the IAS in 1948 (Orissa cadre), rose to become Chief Secretary of Orissa, and held senior Union Government Secretary posts (Information & Broadcasting; Home Affairs) — an administrative-service career from start to finish, capped by governorships including Haryana.

• Jaisukh Lal Hathi was a member of the Constituent Assembly, the Lok Sabha, and the Rajya Sabha, and served as a Union Cabinet Minister across several portfolios — a career built entirely through elections and party politics.

• Dhanik Lal Mandal was a Bihar MLA, Speaker of the Bihar Legislative Assembly, a two-time Lok Sabha MP, and a Union Minister of State — again an elected-political career.

• Babu Parmanand was a Jammu & Kashmir MLA, held several state ministerial portfolios, and was Speaker of the J&K Legislative Assembly — also an elected-political career.

Only Burney's biography traces a pure administrative-service career — IAS officer to Chief Secretary to Union Secretary — while the other three each rose through legislative assemblies, Parliament, and ministerial office. This matches the official HTET 2022 Computer Science paper's published answer key, which also selects Muzaffar Hussain Burney as the Governor who was a civil servant.
