D. d. Statement-1 is false, statement-2 is true

Answer

To analyze the two statements regarding ventilators, we will evaluate each statement step by step.

**Step 1: Evaluate Statement-1**
- Statement-1 claims that "Ventilators are provided at the top of the room."
- This statement is correct. Ventilators are typically installed at the top of a room because hot air rises. When the air inside a room gets heated, it becomes less dense and rises to the top.

**Step 2: Explain the Function of Ventilators**
- The primary function of a ventilator at the top of the room is to allow the hot air to escape. As the hot air exits through the ventilator, it creates a low-pressure area that allows cooler air to enter the room from the lower openings, such as windows or doors. This process helps in maintaining air circulation and temperature balance in the room.

**Step 3: Evaluate Statement-2**
- Statement-2 claims that "Their purpose is to bring oxygen for breathing."
- This statement is incorrect. While ventilators assist in air circulation, they do not specifically bring oxygen into the room. The oxygen needed for breathing primarily enters through windows or doors, where fresh air can flow in from outside.

**Step 4: Conclusion**
- Therefore, we conclude that Statement-1 is true, while Statement-2 is false. The correct answer is that Statement-1 is true and Statement-2 is false.

### Final Answer:
- Statement-1: True
- Statement-2: False
