reduces substantially
does not change
increases heavily
vary continuously

At the time of short circuit, the current in the circuit increases heavily.
Explanation:
During a short circuit, resistance reduces to almost zero. By Ohm's Law,
V = IR
Since V remains the same and R is reduced significantly, current suddenly increases.
