Assertion (A): When a body A at temperature 50∘C is brought in contact with a body B at temperature 30∘C, heat flows from the body A to the body B.
Reason (R): Heat always flows from a body at lower temperature to a body at higher temperature.
a. Both A and R are true and R is the correct explanation of A.
b. Both A and R are true but R is not the correct explanation of A.
c. A is true but R is false.
d. A is false but R is true

Answer:
C is you answer
Explanation:
Answer:
The Correct Answer would be c. A is true but R is false. It means that the Assertion here is true, but the Reason is incorrect.
Explanation:
In the given question, Assertion is true as the heat is flowing from a body kept at a higher temperature to a body kept at a lower temperature. According to the properties of heat, it tends to flow from higher temperature to lower temperature in order to achieve equilibrium. When we take out a bottle kept in freezer and store it outside it for sometime, we eventually notice that the water slowly becomes neutral. It is because of the energy flow in the form of the heat from the surroundings(which are at higher temperature compared to bottle) in the bottle.
Therefore, here assertion is true and reason is wrong.
