Answer:

The correct answer is option B.  "micropipette".

Explanation:

Micropipette is an essential laboratory apparatus to transfer a defined amount of liquid from one reservoir to another. The micropipettes are highly accurate and precise with different ranges of volumes to fit to the operator necessities. A specialized technique, such as the polymerase chain reaction that Ricardo is performing, requires the use of micropipettes to measure and transfer microliters of solutions.
