What are the characteristics of the definite current overcurrent relay overcurrent relay?

A. The relay will work. When detecting that the Fault current is equal to or exceeds the set current value and there is a time to work as an inversely proportional to the amount of current
B. The relay will work. When detecting that the Fault current is equal to or exceeds the set current value and has a variable working time according to the amount of faulty currents
C. The relay will work. When detecting that the Fault current is equal to or exceeds the set current value the relay will work immediately, not depending on the current value.
D. The relay will work. When detecting that the Fault current is equal to or exceeds the set current value the relay will work with a fixed delay time according to the set value.
