Answer :
There is very little resistance and a large amount of current flows in a short circuit. The correct option is a.
What is resistance?
A circuit's electrical resistance is the ratio of the operating voltage to the current flowing through all of it.
When electrons pass throughout a conductor, such as a metal wire, an electric current flows.
Electrons in motion can collide with ions in the metal. This makes the current flow more difficult and causes resistance.
A short circuit has very little resistance as well as a large amount of current flows.
Thus, the correct option is a.
