Best answer
Right answer is (d) Overload of engine

The best explanation: Deficiencies in an indicator diagram are classified into many types. Deficiencies can be determined using the card diagram. Card diagram contains maximum firing pressure and compression pressure. In deficiency 4, compression pressure is high and peak pressure is also high leading to the overload of an engine.
