Answer:
The correct option is: a. 0.12ml, p200
Explanation:
A pipette is a laboratory instrument, which is used to measure and transfer a particular volume of liquid. A pipette comes in various designs with differing levels of precision and accuracy.
An air displacement micropipette is an adjustable micropipette that can deliver about 0.1 µl to 1000 µl (1 ml) of liquid, depending upon the size.
A micropipette type P200 can deliver 20–200 µl liquid.
Therefore, a P200 micropipette is used for measuring 0.12ml or 120µl liquid.
