This is a multiple choice answer as classified in NCERT Exemplar
(b), (d) Tx=Ty when x and y are in thermal equilibrium.
Tx TZ when x and z are not in thermal equilibrium.
Ty TZ
Hence y and z are not In thermal equilibrium.
Given Tx Ty
And Tx TZ
We cannot say about equilibrium of y and z.
They may or may not in thermal equilibrium
