Answer:
A) Because filament is made of some properties like high melting point and high resistance. So heat produced is derictly proportional to resistance and heat get transformed into light so the filament glows but electric wire may not have these properties.
B) The specific heat capacity of the filament of the bulb is too high .
It is made up of tungstun. So a lot of heat i required to raise its temperature.
That is why the filament does not get burnt at 2700degree celsius
