Concept:A three-pin plug has standard colour coding and safety connections for live, neutral, and earth wires.
Explanation:Check each statement one by one.
Statement i says the brown wire is the live wire.
In the standard wiring colour code, brown is indeed the live wire.
So statement i is correct.
Statement ii says the fuse is connected to the live wire.
The fuse is always placed in the live wire so it can break the circuit if too much current flows.
So statement ii is correct.
Statement iii says the earth wire is coloured blue.
Actually, the earth wire is green or green/yellow, while blue is the neutral wire.
So statement iii is incorrect.
Therefore, only statements i and ii are correct.
Answer:Statements i and ii only are correct, which is option C.
