I would say that this answer is not completely correct as even though turbochargers use the same concept but there we increase the fuel supplied in accordance with air so as to get higher output from same engine size, but here oxygen remains same.
I would suppose B to be a better match as less heat addition would be required to increase temperature of intake gas.

Turbocharger is a turbine driven device that increases an engine's efficiency and power by forcing extra air into the combustion chamber, the turbine can force more air and proportionately more fuel into the combustion chamber that atmospheric pressure alone.

The actual work of turbocharges is to increase the inlet pressure. Therefore increasing pressure would be a cause an increase in temperature would be an effect. Here, it is asked about cause not the effect. Hence the answer C is valid.

When the pressure of inlet air is high, more amount of air can be accommodated in the cylinder which will result an increase in the O2 content and will provide a better combustion. This will increase the output power.

Increase in pressure leads to rise in temperature, which proves to be useful for the compression ignition of fuel. Also a large volume of air is intake, which increase the oxygen availability.

Break power depends on pressure & temperature. So increase in press increases temp & indirectly B.P. also.

Usually turbocharger is used to increase the pressure of intake air by utilising the waste exhaust gas.

Please give the Brake power formula with detail explanation.
Thank you.
Thank you.

B.P = pmlan/60, where pm = break mean effective pressure.

By supercharger intake the air pressure increases.
