Verified Answer
Two blocks which are at different states are brought into contact with...
A and C are in thermal equilibrium.
B and C are in thermal equilibrium.
A and B are also in thermal equilibrium with each other.
so, final temperature attained is specified by "Zeroth law of thermodynamics."

Two blocks which are at different states are brought into contact with...
Explanation:
When two blocks at different temperatures are brought into contact with each other, they eventually reach a state of thermal equilibrium, i.e., they attain the same temperature. This is based on the zeroth law of thermodynamics.
Zeroth Law of Thermodynamics:
The zeroth law of thermodynamics states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. This law establishes the concept of temperature and provides a basis for temperature measurement.
First Law of Thermodynamics:
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted from one form to another. This law is also known as the law of conservation of energy.
Second Law of Thermodynamics:
The second law of thermodynamics states that the total entropy of an isolated system always increases over time, approaching a maximum value at equilibrium. This law is also known as the law of entropy.
Third Law of Thermodynamics:
The third law of thermodynamics states that as the temperature of a system approaches absolute zero, the entropy of the system approaches a minimum value. This law is also known as the Nernst heat theorem.
Therefore, the correct answer is option 'A' as the zeroth law of thermodynamics explains the process of two blocks at different temperatures reaching a state of thermal equilibrium.

Two blocks which are at different states are brought into contact with...
Zeroth law of thermodynamics state that "when the body A is in thermal equilibrium with body B and body B is in thermal equilibrium with body C SEPARATELY( no direct contact) ,then A and C are in thermal equilibrium" .
