A6. Plastics with a size of 300 micrometers to 5 millimeters are called microplastics. Which of the following sizes is not within this range?
(A) $4 \cdot 10^{-4} \mathrm{~m}$
(B) $4 \cdot 10^{-6} \mathrm{~m}$
(C) $4 \cdot 10^{-3} \mathrm{~m}$
(D) $4 \mathrm{~mm}$
(E) $4 \cdot 10^{-2} \mathrm{~cm}$
A6. Microplastics are in the size range of $0.3 \mathrm{~mm}$ to $5 \mathrm{~mm}$. In this range, $4 \cdot 10^{-6} \mathrm{~m}$ does not fall.
