Text Solution
Verified by ExpertsThe correct answer is:
A
According to Zeroth law of thermodynamics, two systems in thermal equilibrium with a third system separately are in thermal equilibrium with each other. So, if 
and 
are separately in equilibrium with 
, then 
and 
. This implies that 
, i.e. the systems 
and 
are also in thermal equilibrium.
