Paticulate bigger than `x` microns are likely to lodge in the nasal passage whereas particles of about `y` microns enter to the lungs easily `x` and `y` are

Options

A. `x=5,y=0.10`
B. `x=5,y=1.00`
C. `x=5,y=0.30`
D. `x=6,y=0.20`

Answer

B

Explanation

Paticulate pollutants `gt5` microns are likely to lodge in the nasal passage.
Particulate pollutants `lt1` micron, enter into lunges easily.
If `xgt5` microns-nasal passage is blocked.
`y le1` micron-enter into lungs.
