LOOOL! Actually, it's definitely not 1A because the hair drier needs 2A.. so that's why it's B which is a fuse of 3A
However, on our exam... the lamp needed 0.25 to light at maximum brightness... and the wire can carry up to 5A. So it was neither 0.2A, 5A, nor 10A.... because 1A is the most suitable.

But didnt they ask for THE OTHER END, that means the fuse is for the wire, so 10A was my answer
