Thermal equilibrium means, temperature of the two body or system is same.
And if the temperature is same then, there is no heat transfer.
Here given, X and Y are in thermal equilibrium, and Z have have temp. to that of Y. So all X,Y,Z will be in thermal equilibrium.
So last option,
There is no net transfer of energy if X is placed in thermal contact with Z. Is correct.
