Answer:
[tex]\boxed{\text{b. P200; 055}}[/tex]
Explanation:
1. Type of pipette
The three most common types of micropipette are shown in the table below.
[tex]\begin{array}{ll} \textbf{Type} &\textbf{V/ $\mu$L }\\ \text{P20} & 2 - 20 \\ \text{P200} & 20 - 200 \\ \text{P1000} & 200 - 1000 \\ \end{array}\\ \text{The only type that will dispense 55 µL is the $\boxed{\textbf{P200}}$}[/tex]
2. Window
The window on a P200 micropipette shows three digits.
The first digit is hundreds, the second is tens, and the third is units of microlitres.
A measurement of 55 µL will display as 055.
