    Explanation:

    - Water's high specific heat allows it to absorb a lot of heat before it turns to steam, which helps cool down the burning material.

    - When water turns into steam upon contact with fire, it expands and forms a barrier, cutting off the oxygen supply that is essential for the fire to continue burning.

    - High specific heat and steam formation are both critical to extinguishing fires effectively.

    ?? The correct option is: Option 3 – Both 1 and 2
