The ideal cycle with the lowest thermal efficiency for specified limits of the maximum and minimum temperatures is the Diesel cycle.

Here's why:

a. Carnot Cycle: This is the most efficient cycle because it is a reversible cycle (no energy losses). It consists of two isothermal processes and two adiabatic processes.

b. Stirling Cycle: This cycle is also very efficient. It consists of two isothermal processes and two constant volume processes.

c. Ericsson Cycle: This cycle is similar to the Stirling cycle but it consists of two isothermal processes and two constant pressure processes. It is also very efficient.

d. Diesel Cycle: This cycle is less efficient than the Carnot, Stirling, and Ericsson cycles. It consists of two adiabatic processes, one constant pressure process, and one constant volume process. The reason it is less efficient is because the heat addition process is not isothermal, which is less efficient.

e. All are the same: This is not correct because, as explained above, the efficiency of these cycles is not the same.

So, the answer is d. Diesel.
