Which one of the following pairs is not correctly matched, as per the Central Industrial Security Force Amendment Act, 1983 ?

The Central Industrial Security Force (Amendment) Act, 1983, formally declared the CISF as an Armed Force of the Union and updated the designations of its members to align with standard armed force ranks. Section 14 of the Amendment Act provided a specific mapping for existing personnel:

• Chief Security Officer was redesignated as Commandant.
• Security Officer was redesignated as Assistant Commandant.
• Head Security Guard was redesignated as Head Constable.
• Senior Security Guard was redesignated as Naik.
• Security Guard was redesignated as Constable.

Option C is the incorrect match because the Act designates the Head Security Guard as a Head Constable. The rank of Constable was assigned to those previously designated as Security Guards.
