Efficiency of a heat engine working on Carnot cycle between two temperature levels depends upon the Correct Answer Two temperatures only

Efficiency of a Carnot engine is given as $$\left( {{T_1} > {T_2}} \right)\aleph = 1 - \frac{{{T_2}}}{{{T_1}}}$$
So, it's solely dependent on temperatures of the reservoirs.
