Option 1 states that both the Assertion (A) and the Reason (R) are individually true and that R is the correct explanation of A.

To evaluate this option, let`s first assess the accuracy of each statement on its own. The Assertion (A) states that steam is more harmful to the human body than boiling water in case of a burn. This statement is true because steam has the ability to transfer more heat energy to the body, leading to deeper and more severe burns compared to burns caused by boiling water.

The Reason (R) states that boiling water contains more heat than steam. This statement is false. Boiling water and steam both have the same temperature; therefore, they contain the same amount of heat energy. The difference lies in the physical state and the heat transfer properties of water and steam. Steam has a higher heat transfer rate due to its gaseous state, allowing it to carry more heat energy and cause more severe burns.

Since the Reason (R) is false, it cannot be considered as the correct explanation of the Assertion (A). Therefore, option 1 is incorrect.

Option 2 states that both the Assertion (A) and the Reason (R) are individually true but that R is not the correct explanation of A. This
