The answer you can give is:
The health and safety at work Act 1974 and the Electricity at work regulations 1989.
I could suppose that the Act is an act not a regulation and therefore they may be wanting, say, The management of health and safety at work regulations 1999.
The question states "give two health and safety regulations" therefore to answer you give two health and safety regulations.
The reference to a socket on a ring final is just to show you are working with electrical equipment. Ah... you could also give The Electrical Equipment (Safety) Regulations 1994.
It is a poorly worded question but typical of the prevarication provided by city and guilds.
