Answer 2

The correct answer is option d. all of the above.

The particulate control device is a device, which is used to separate the material, which size is bigger. The size of the particulate to be separated can be changed according to the purpose it is used.

In factory smoke stack, the particulate control device filters the particles, which can pollute the air. In vacuum cleaner, the fine dust and the large particles are separated. In laundry dryer, the particulate filter allows the entrance of water and dirt only, so that the clothes remain separate. Hence, all of the above is the correct answer.
