Carnot efficiency of engine 
But according to the inventor‟s Claim
Efficiency of engine = 1-0.45 = 0.55
Efficiency of engine = 1-0.45 = 0.55
∴ Efficiency of Actual Engine cannot be greater than Carnot efficiency. So this is an impossible engine

The correct answer is option 'C' - an impossible engine. Let's analyze each option and determine why the inventor's engine falls under this category.
a) Carnot engine:
A Carnot engine is an ideal heat engine that operates between two temperature limits where all the heat absorbed from the source is converted into work. This means that a Carnot engine does not reject any heat. Since the inventor's engine rejects 45% of the heat absorbed, it cannot be equivalent to a Carnot engine.
b) Diesel engine:
A Diesel engine is a compression-ignition internal combustion engine that operates on the diesel cycle. It absorbs heat during the combustion process and converts it into work. However, a Diesel engine does not reject a significant portion of the heat absorbed. Therefore, the inventor's engine cannot be equivalent to a Diesel engine.
c) An impossible engine:
The correct answer is option 'C' because the inventor's engine violates the fundamental principle of thermodynamics, which states that heat cannot flow from a lower temperature region to a higher temperature region without the input of external work. In this case, the inventor's engine rejects heat while operating between temperature limits of 27C to 327C. By rejecting heat, the engine is effectively transferring heat from a low-temperature region (the surroundings at 27C) to a high-temperature region (the source at 327C) without any external work input. This violates the second law of thermodynamics and is considered an impossible engine.
d) Ericsson engine:
An Ericsson engine is a type of external combustion engine that operates on the Ericsson cycle. It involves the continuous heating and cooling of a working fluid to produce work. While the Ericsson engine can reject some heat, it does not reject a significant portion like the inventor's engine. Therefore, the inventor's engine cannot be equivalent to an Ericsson engine.
In conclusion, the inventor's engine falls under the category of an impossible engine because it violates the fundamental principles of thermodynamics.
a) Carnot engine:
A Carnot engine is an ideal heat engine that operates between two temperature limits where all the heat absorbed from the source is converted into work. This means that a Carnot engine does not reject any heat. Since the inventor's engine rejects 45% of the heat absorbed, it cannot be equivalent to a Carnot engine.
b) Diesel engine:
A Diesel engine is a compression-ignition internal combustion engine that operates on the diesel cycle. It absorbs heat during the combustion process and converts it into work. However, a Diesel engine does not reject a significant portion of the heat absorbed. Therefore, the inventor's engine cannot be equivalent to a Diesel engine.
c) An impossible engine:
The correct answer is option 'C' because the inventor's engine violates the fundamental principle of thermodynamics, which states that heat cannot flow from a lower temperature region to a higher temperature region without the input of external work. In this case, the inventor's engine rejects heat while operating between temperature limits of 27C to 327C. By rejecting heat, the engine is effectively transferring heat from a low-temperature region (the surroundings at 27C) to a high-temperature region (the source at 327C) without any external work input. This violates the second law of thermodynamics and is considered an impossible engine.

An Ericsson engine is a type of external combustion engine that operates on the Ericsson cycle. It involves the continuous heating and cooling of a working fluid to produce work. While the Ericsson engine can reject some heat, it does not reject a significant portion like the inventor's engine. Therefore, the inventor's engine cannot be equivalent to an Ericsson engine.
In conclusion, the inventor's engine falls under the category of an impossible engine because it violates the fundamental principles of thermodynamics.
