All living organisms are made of cells. The smallest living cell has a diameter of $$\(0.2 \mu \mathrm{~m}\)$$. The volume of a sphere is calculated using the formula: $$\[ \frac{4}{3} \pi r^{3} \]$$ Which of the following shows the volume of this cell in standard form? (1)

A.
\(4.2 \times 10^{-3} \mu^{3}\)
B.
\(4.2 \times 10^{3} \mu \mathrm{~m}^{3}\)
C.
\(3.4 \times 10^{-2} \mu^{3}\)
D.
\(3.4 \times 10^{2} \mu \mathrm{~m}^{3}\)
