A. $2\times10^{-6}$ .

Step-by-step explanation:

Given: The diameter of bacterium = 0.0000029 meter

≈ 0.000002 meter [ with 6 decimal places]

$=\dfrac{2}{1000000}=\dfrac{2}{10^6}$

$=2\times10^{-6}$ meters [ $\dfrac{1}{a^n}=a^{-n}$ ]

i.e. $2\times10^{-6}$ closest to 0.0000029.

Hence, the correct option is A. $2\times10^{-6}$ .
