Explanation:
i know my brother said it
 
        
             
        
        
        
The answer is d, gravity is the only force acting on the object
        
             
        
        
        
 = Heat released to cold reservoir
 = Heat released to cold reservoir
 = Heat released to hot reservoir
 = Heat released to hot reservoir
 = maximum amount of work
 = maximum amount of work
 = temperature of cold reservoir
 = temperature of cold reservoir
 = temperature of hot reservoir
 = temperature of hot reservoir
we know that 

 eq-1
                                eq-1
maximum work is given as 
 =
 =  -
 - 
using eq-1
 =
 =   -
 -
