Solution
The correct option is D Breaking of filament of bulb due to overloading
An electric bulb may fuse due to
many reasons. One reason for a bulb to
fuse is a break in its filament. A break
in the filament of an electric bulb means
a break in the path of the current
between the terminals of the electric cell. When excess electricity or too much current passes through the circuit, it causes overheating and because of overheating the filament wire of bulb melts and then bulb gets fuse.This is the reason why suddenly the light bulb fuses while Seema went to Usha's house to complete the project work given in the school.
