Answer : The correct option is, a volumetric pipette

Explanation :

Volumetric pipettes : It is a type of instrument that are used in volumetric analysis. It is used for the exact smaller volume of a sample solution or a reagent.

In the volumetric pipette, the upper part of the pipette has a ring like mark that marks its calibrated volume.

Burette : It is used in the titration for the known concentration of the solution.

Beaker : It is not used in the titration because it is not accurate for the measurement.

Erlenmeyer flask : It is a conical flask which is also used in the titration.

Hence, a volumetric pipette instrument is most often used to measure acid volume before a titration begins.
